Description Alin M Elena 2013-04-04 22:18:07 UTC 
Application: kwin (4.10.60 "release 101")
KDE Platform Version: 4.10.60 "release 101"
Qt Version: 4.8.4
Operating System: Linux 3.9.0-rc5-1-desktop+ x86_64
Distribution: "openSUSE 13.1 Milestone 0 (x86_64)"

-- Information about the crash:
on a kde trunk install with nouveau kwin crashes at startup...
It is almost always but not always dr konqi comes out.

sometimes the effect is that desktop effects are not active anymore... and I am back to Xrender/native instead of my original settings of opengl/raster

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault

Comment 1 Thomas Lübking 2013-04-04 22:39:34 UTC 
a) Does this *only* happen in the session start?
b) Does this crash *not* happen with the XRender compositor?
(not uncomposited, native graphicssystem is so far preferred with XRender compositing)
Comment 2 Alin M Elena 2013-04-04 22:48:34 UTC 
a) yes... or at least that was the only time I have seen it...
b) I do not use xrender... always set it to opengl.. my observation that the compositor changes to xrender from opengl may be not related with the bug... i just noted it.

Comment 3 Thomas Lübking 2013-04-04 22:56:50 UTC 
I'd ask you to try the XRender compositor to determine whether this is a memory corruption in (likely) the nouveau driver or a dangeling pointer in the AnimationEffect class....
Comment 4 Martin Flöser 2013-05-07 15:19:24 UTC 
waiting for the test with XRender
