Bug 263746

Application: kwin (4.5.5 (KDE 4.5.5) "release 1")
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:every time i boot in 4.5.5 

- Unusual behavior I noticed: cant view clearly anything a complete mess 

- Custom settings of the application:the solution is to go to system settings  and click suspend Desktop effects then everything is ok

The crash can be reproduced every time.

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