Bug 265960

Application: kwin (4.6.00 (4.6.0) "release 375")
KDE Platform Version: 4.6.00 (4.6.0) "release 375"
Qt Version: 4.7.1
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

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

I was watching a flash video stream on full screen.  I pressed the "Escape" key to leave full screen mode and kwin crashed.

The crash can be reproduced some of the time.

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