k3b doesn't launch!!

[stereosit]

After a properly upgrade from kubuntu 9.04 to kubuntu 10.04 -where everything seems to be fully working at first glance!- I found an insidous problem with k3b:

it's installed but when I try to run it nothing happens... If I try it from konsole, i obtain:
$ k3b
(...nothing happens... no prompt... no stdout... no stderr)

if i open at the same time another console, with ps I get this:

alfonso 10997 0.0 0.6 69132 13224 pts/1 S+ 10:39 0:00 k3b
alfonso 10998 0.0 0.0 0 0 pts/1 Z+ 10:39 0:00 [k3b] <defunct>

Any suggestions?!

Thanks in advance!

Re: k3b doesn't launch!!

Hmmm...upgrading by "jumping" one release is never a good idea.

First try deleting: /home/yourusername/.kde/share/apps/k3b
(.kde is hidden so you will have activate hidden files in dolphin->view)

and relaunching k3b.

If that doesn't help try purging k3b and reinstall it:

sudo apt-get remove --purge k3b

sudo apt-get install k3b

I hope that helps

Re: k3b doesn't launch!!

I think this is a 2.6.32 kernel problem related... On the same session I installed brasero (and all its dependencies) and got the same problem...

I rebooted the machine, and from grub menu I choosed 2.6.31 kernel, and everything worked properly (in fact now i'm burning a dvd with k3b with doing anymore).

Another issue related to 2.6.32 kernel i've found is that compiling and upgrading modules of vmware player for that kernel gives error when trying to compile network services (no problem with older kernel again).

Any other here has the same problem?

Re: k3b doesn't launch!!

K3b works fine here on 2.6.32 kernel.

For vmware you will have to install the 2.6.32 kernel headers (don't know why they are not installed by default ) and it compiles fine.

Re: k3b doesn't launch!!

More ideas:

- kill all k3b processes:

killall k3b

- try again from the command line (just for fun and to see whether you get any decent info out of it)

If nothing has come of it, you may want to install strace and start k3b with it for serious error reporting:

sudo apt-get install strace
strace k3b

Here it comes the strace k3b output:

Another (maybe little) help: when I choose kernel 2.6.32-21 from grub menu, it appers for a few moment on the top of the screen a message saying:

disabling IRQ#(and a long number here that i couldn't copy for now)

when choosing kernel 2.6.31-21 it doesn't appears this warning.

Thanks!

Re: k3b doesn't launch!!

Could you please use pastebin for the strace output?

Thanks

Cheers!

But is that all? It ends rather innocuously in ...mmap2(NUL

No segmentation fault or nothing. Have you tried Fintan's suggestion of purging and reinstalling?

Yes I did it; nothing happens again... when launching k3b from K menu the icon is bouncing for a while and then dissapears; doing ps again k3b <defunct>...

I keep on thinking this a kernel related issue (remember brasero -clean installation- is doing the same; not lauching after a while).

Any other suggestion?

Thanks in advance

Re: k3b doesn't launch!!

I have a suspicion that by upgrading from 9.04 to 10.04 you have some residue k3b files flying around.
This happens often enough when upgrading from the previous version to the next (why I always do a clean install ) Upgrading from two versions away can be and usually is more of a pain.

K3b has evolved since 9.04 considerably and probably doesn't like those old files.

You could go thought the folder k3b installs to and try and find the offending files:

/usr/bin/k3b
/usr/bin/k3bsetup
/usr/share
/usr/share/applications
/usr/share/applications/kde4
/usr/share/applications/kde4/k3b.desktop
/usr/share/doc
/usr/share/doc/k3b
/usr/share/doc/k3b/FAQ
/usr/share/doc/k3b/README
/usr/share/doc/k3b/README.Debian
/usr/share/doc/k3b/TODO
/usr/share/doc/k3b/changelog.Debian.gz
/usr/share/doc/k3b/changelog.gz
/usr/share/doc/k3b/copyright
/usr/share/man
/usr/share/man/man1
/usr/share/man/man1/k3b.1.gz
/usr/share/menu
/usr/share/menu/k3b
/usr/share/pixmaps
/usr/share/pixmaps/k3b.xpm

or lust do a clean instal and bedone with it.

If you have /home/username on a separate partition (always a good idea ) you shouldn't have any problems. If it is in / the back up your /home/username first and maybe think about creating a seoarate /home while you are at it. Use the gparted live cd for this:
http://gparted.sourceforge.net/download.php

or better yet parted magic live CD:
http://partedmagic.com/download.html

good cd's to keep around in case of data emergency.

Hope all this helps

Re: k3b doesn't launch!!

Another little help:
when launching k3bsetup from console I obtain:

alfonso@pcalfonso2:/usr/bin$ k3bsetup 
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No existe el fichero ó directorio
QFileSystemWatcher: failed to add paths: /home/alfonso/.config/ibus/bus
Bus::open: Can not get ibus-daemon's address. 
IBusInputContext::createInputContext: no connection to ibus-daemon

Finally I could launch brasero but didn't recognize any dvd burner, so I keep on thinking some kernel module can't load or detect or someover similar my dvd burner and this is confusing k3b.

Thanks in advance!

Re: k3b doesn't launch!!

As far as i know (which isn't much) k3b and brassero use the same backend engine.

If this is borked (upgrade issue) then they will not work.

It could be kernel issue as I have just upgraded my kernel to .22 and get a "install new apps for k3b->codecs message on opening k3b. When I want to go for install it gives an error.

then again from terminal I get this:

fintan@fintanws2:~$ k3b
k3b(3033)/kdecore (KLibrary) kde4Factory: The library "/usr/lib/kde4/k3bffmpegdecoder.so" does not offer a qt_plugin_instance function.
k3b(3033)/kdecore (KLibrary) kde3Factory: The library "/usr/lib/kde4/k3bffmpegdecoder.so" does not offer an "init_k3bffmpegdecoder" function.

k3b(3033)/kdeui (kdelibs): Attempt to use QAction "location_bar" with KXMLGUIFactory!
fintan@fintanws2:~$

I don't have DVD's to test for now but maybe later.

Edit:

I get the same message and out put on kernel .21 but it is burning a movie DVD right now.

Re: k3b doesn't launch!!

almost solved...

Curious thing: I took a konsole this morning doing test with this issue and on a session i launched /usr/bin/k3bsetup... and left there (doing nothing... the previous and similar messages); I went to a meeting and when returning to the office I FOUND K3BSETUP OPEN (at last took 20 minutes to open); so I did the same with k3b and finally moreover 30 minutes it launched properly...

So, what can it be happening here?

Thanks in advance!

Re: k3b doesn't launch!!

Open a Konsole window and run "top", and then place it on the screen where you can observe it. Then open another Konsole window. or just use Alt-F2 and launch K3b, while watching the "top" window. I assume something is sucking up all the resources and slowing down the launch of K3b (or anything else, probably).
