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:
Watched an online flash video fullscreen (Firefox 4 & Adobe flash). When switching back to window mode kwin crashed.

- Unusual behavior I noticed:
During the video a few times the screen flickered or stopped, forcing me to switch back to the browser and continue from there.

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