[SOLVED] systemsettings > workspace appearance crashes

[doctordruidphd]

I have been trying to do some cleanup on my system, and evidently yanked something I shouldn't have (thank you, autoremove). Whenever I attempt to open SystemSettings > Workspace Appearance, I get a crash of the system settings program.

Edit: This behavior continues even if I remove the ~/.kde directory.
I know I did remove several gnome themes, looks like all the kde themes are still there.
Some package I need to reinstall to fix this?

Here is the backtrace:

Application: System Settings (systemsettings), signal: Segmentation fault

Drawing a blank on the specifics, but I recently had to remove qtcurve stuff to fix a crash of Application Appearance, and I think Workspace Appearance.

[doctordruidphd]

Thanks, Application Appearance seems to be working fine.

[sumski]

4.9, right?

You need to recompile bespin, or wait until RC2:
http://quickgit.kde.org/index.php?p=...23a69fc09bdfeb
http://quickgit.kde.org/index.php?p=...2e5deff5a789b3

[doctordruidphd]

This is kde-4.8.80 on precise 12.04.
I made a complete system backup prior to hacking away at gnome and unity; I booted into the backup system, and it has the same problem. So it is evidently not something I did.
I guess I wait. Thanks for the info.

[doctordruidphd]

Problem solved with upgrade to kde-4.8.90.

[doctordruidphd]

OK, I spoke a little too soon.
I removed all of the kwin-styles that were installed from the repositories, and Workspace Appearance is still crashing.
There is still a lot of stuff in /usr/share/kde4/apps/kwin
What should I remove?

Edit:

Found it. /usr/lib/kde4/kwin3_bespin.so

[sumski]

How did you install bespin?

[doctordruidphd]

I don't remember where I got it, it's been there for a while. I am guessing it came from the "get new decorations" button, but it's possible I downloaded it from kde-look.

[sumski]

It's either self-compiled, or from a PPA, it's not a ready-to-go binary.

[doctordruidphd]

Yeah, I'm pretty sure I didn't compile it. Must have come from a ppa (yours?).

Look at the changelog

This is what I have at the top of the changelog -- looks like it's from you, but it's old. Has the problem been fixed?

[sumski]

You have the same revision, ~1582 (that first number is just a date+time), but:
a)Built for Precise (not a problem)
b)Built against KDE 4.8.4, not 4.9 (problem)
I've just pushed a build into backports-kde-goodies PPA, so update should come soon to that PPA, you can either add it, or just grab the .deb
