Bug 292467

Application: dolphin (1.7)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.2.0-10-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was browsing file structure, i click on a directory to explore it, then Dolphin crashes every time.

- Unusual behavior I noticed: I can't activate KDE Desktop Effects, it crashes KDE

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
