Application: kwin (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

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

I was trying to fix a config problem in the mars-shoter game. Everytime the game went full screen Kwin crashes (And I equally got this problem when I launch full screen flash videos, but in this case Kwin didn't crash at each attempt to go fullscreen).

I cannot remember if I got this problem before I migrate to Natty but I don't think this could be the cause of the crashes.

I'm on a fujitsu Lifebook A530, under Kubuntu.

The crash can be reproduced every time.

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