Application: systemsettings (1.0)
KDE Platform Version: 4.8.80 (4.8.80)
Qt Version: 4.8.1
Operating System: Linux 3.4.0-030400-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I opened System Settings, clicked on Workspace Appearance and it crashed.
Probably related to Oxygen Transparent being installed?
DrKonqui presented me a similar bugreport that was about KWin crashing on startup with it.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
