midnight commander crash

[drac]

Hi all,

I'm experiencing some crashes with mc in kubuntu 7.04.

My LANG variable is en_US.UFT-8

To reproduce, hold ctrl-o for a few seconds to switch from normal mode to command line mode.

Then the crash comes, here is the screenshot with the errors:

Ooops ... and what does locale result in?

USER # locale
LANG=en_US.UTF-8
LC_CTYPE=en_US.UTF-8
LC_NUMERIC=de_CH.UTF-8
LC_TIME=de_CH.UTF-8
LC_COLLATE=en_US.UTF-8

(I prefer a "swiss-english" environment ...)

Re: midnight commander crash

To reproduce, hold ctrl-o for a few seconds

I tried - but the **** thing refuses to die

Have you tried to reinstall the mc package?

Any other console tools behaving strangely?

[drac]

Re: midnight commander crash

I reinstalled it, recompiled it, I recompiled a debian version, no luck.

Mc dies in konsole, xterm, putty over ssh, it's really creepy. It only happens on my system

It starts by having garbage characters in the window title bar, representing the home directory, and after doing some work.. bum. (keeping ctrl-o pressed is a fast way to reproduce the bug)

Mc is the only thing keeping my kubuntu 7.04 from achieving the goal of a perfect desktop

Edit:
It doesn't crash in console mode, only when I'm in X or over ssh, strange.

Re: midnight commander crash

It doesn't crash in console mode

It's a console tool, after all

Plan B: [Alt][F2] xterm mc

Re: midnight commander crash

Found it!

As I was saying, the titlebar of konsole had fuzzy characters. Well, that was the clue in finding the problem.

22_main.c.patch does change the update_xterm_title_path to include the user name and the current directory. This patch is flawed on my system.

I removed the patch and the crash is gone. When I'll have some time I'll investigate why the patch doesn't work.

Cristi.

Re: midnight commander crash

22_main.c.patch

Patch? What patch??

[drac]

Re: midnight commander crash

Mc is a very patched package.

If you install the source package with: apt-get source mc you will get three files:
'mc_4.6.1.orig.tar.gz'
'mc_4.6.1-7ubuntu1.diff.gz'
'mc_4.6.1-7ubuntu1.dsc'

After you unzip and apply the patch archive you will have in directory mc_4.6.1/Debian/Patches allot of patch files.

There I removed 22_main.c.patch.diff and recreated my mc package with dpkg-buildpackage -rfakeroot.

That patch doesn't do much, I don't care much if I don't see my username in the
xterm console name.

BTW I get errors when trying to reply from Konqueror: "Your session timed out while posting. Please try to re-submit your message."
