Bug 304434

Application: systemsettings (1.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.1
Operating System: Linux 3.5.0-7-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Clicking "Appearence" in system settings causes kwin decoration settings to segfault. Without kwin-style-dekorator (0.5.1-1ubuntu1) installed everything is ok.

- Custom settings of the application:
oxygen-transparent installed

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings), signal: Segmentation fault
