Bug 264989

Application: kwin (4.6.00 (4.6.0))
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: starting kde with kwin effects activated, after installing the Intel EMGD drivers for the poulsbo chipser.

- Unusual behavior I noticed: kwin crashed. Afterwards, screen efects are disabled due to technical reasons.

- Custom settings of the application: none

The crash can be reproduced every time.

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