Bug 325729

Application: kwin (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-31-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I was creating a separate window rule to workaround https://bugs.kde.org/show_bug.cgi?id=325700

- Custom settings of the application:
There is a rule to disable decorations and as suggested in https://bugs.kde.org/show_bug.cgi?id=325726 I've changed PluginLib to oxygen.

$ kreadconfig --file kwinrc --group Style --key PluginLib
oxygen

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
