Application: systemsettings (1.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.35.14-97.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
This is a fresh FC14 x86_64 installation. I was configuring in the "Classic style" settings when this crash happened.

Sometimes the display on the left side appears greyed out but the items are still selectable. The size of the left side is configurable by dragging an "area" on it's right side to the left or right but this fails sometimes.

The crash can be reproduced every time.

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