Bug 319758

Application: kwin (4.10.2)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.11-200.fc18.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Exiting XBMC in full screen mode causes KWin to crash. This is not consistently reproducible, but happens about 50% of the time.

XBMC version is 12.1-2.fc18

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
