Bug 262001

Application: systemsettings (1.0)
KDE Platform Version: 4.5.4 (KDE 4.5.4)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.10-74.fc14.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I was navigating in the system settings dialogues. Turning on compositing causes a seg fault and subsequent restarts of kde die with seg fault as well.

This problem was NOT related to compositing, just what I would consider "normal" user interaction.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
