Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
just playing openarena-x64, then a wine-game(win32-exe), then again openarena (opengl).
after quit oa kwin gives crash-msg
- Unusual behavior I noticed:
after boot(restart)/login a kscreensaver-window appears/remains on desktop every login although no screensaver was active while shutdown. maybe another topic, but this behavior i noticed since time of installation...

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