Sentry Crash Report:

Description deathpyre.tarrant 2012-12-26 01:25:38 UTC 
Application: krita (2.7 Pre-Alpha)
KDE Platform Version: 4.9.4 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.6.8-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

-- Information about the crash:
- What I was doing when the application crashed:

Went to settings menu, clicked on configure, crashes. Built with gtl enabled, and w/o, same problem.  Saw the known bug with llvm version mis-match, but everything was built with llvm 3.1-r2 from gentoo's main tree.

Current Krita from git, all other calligra apps disabled. Opensource radeon drivers, r600; not sure if opengl is enabled or not, and can't check in the config screen. Has been happening for a long time.

The crash can be reproduced every time.

-- Backtrace:
Application: Krita (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Halla Rempt 2012-12-26 09:05:19 UTC 
It is an opengl problem... But from the backtrace, it's actually happening inside Qt. If you move .kde/share/config/kritarc somewhere else, can you open the settings dialog again?
Comment 2 deathpyre.tarrant 2012-12-27 00:14:02 UTC 
No change after moving $HOME/.kde4/share/config/kritarc.

I wasn't sure if this was opengl or not, as this is the only instance where it has been problematic for me.

Should I file a bug somewhere else?

Comment 4 Sven Langkamp 2012-12-27 00:44:54 UTC 
I have pushed a change that should allow to open the preferences. It will still crash when you enable OpenGL.
Comment 5 deathpyre.tarrant 2012-12-27 03:24:22 UTC 
Rebuilt and it works now, thanks a bunch!

Is there anyplace upstream that might be able to use this bug report? Qt perhaps?

Comment 7 Halla Rempt 2012-12-28 07:08:45 UTC 
We would only be able to report to Qt if we could recreate the problem in a small example application, and the chances of that are slim.
