Application: kwin (4.5.1 (KDE 4.5.1))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Moving mouse to change desktop

- Unusual behavior I noticed:
Frequent crashes of kwin under several circumstances....
1> When watching a video
2> When changing desktop
3> Using KDevelop

Possibly associated a configuration problem gives very slow animations (sometimes)

The crash can be reproduced some of the time.

-- Backtrace:
Application: KWin (kwin), signal: Aborted
