Description Russ Brown 2009-07-21 22:31:10 UTC 
Application that crashed: krita
Version of the application: 2.0.1
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was basically playing with krita when this happened, so this is hopefully close to what I did to cause this:

1. Loaded up an image and looked in the settings.
2. Saw the open GL mode and enabled it.
3. Exited from settings.
4. Saw that the image was garbled.
5. Drew something random on the image with a random tool, then hit undo
6. Went back into settings and turned off Open GL mode
7. Exited from settings and hit undo again
8. Crash

Thanks for your report.
Comment 2 Halla Rempt 2009-09-16 21:38:18 UTC 
Now I need a computer that supports opengl at all to check... Lukas could you check this?
Comment 3 LukasT 2009-09-16 23:08:05 UTC 
I noticed just this:

QObject::connect: Cannot connect KoMainWindow::restoringDone() to (null)::removeUnusedOptionWidgets()

but I could not reproduce the crash.

How reproducible is this crash?
Can you reproduce it again?
Comment 4 Russ Brown 2009-09-16 23:16:31 UTC 
Hmm, unfortunately not. At least, if the bug is still present then I'm not doing the correct steps in order to reproduce it.

I do however still get image garbling when switching opengl mode on and off. Just no crash.

It may be relevant that I am now running krita 2.0.2: maybe the crash problem has been solved in this version?
Comment 5 Halla Rempt 2009-09-20 14:29:50 UTC 
The image garbling may be caused by the graphics card driver -- as you no doubt know, graphics drivers in Linux are currently in a transitionally state from crap to possibly half way decent, but in-between we're in a stage of unbelievable crap.

That said... I might also be a bug in our opengl code. Which graphics card and driver are you using, and do you have a compositing window manager enabled?

With Kubuntu jaunty on an intel gma chip and no desktop effects, I don't get any garbling - but on OpenSUSE with a similar setup, I get a flickering canvas and dialogs aren't shown.
Comment 6 Halla Rempt 2009-09-20 15:16:13 UTC 
The actual crash doesn't seem to occur and the code references in the backtrace doesn't exist anymore.
