Application that crashed: kde4-window-decorator
Version of the application: 0.0.1
KDE Version: 4.3.1 (KDE 4.3.1) "release 3"
Qt Version: 4.5.2
Operating System: Linux 2.6.31-10-desktop x86_64
Distribution: "openSUSE 11.2 Milestone 8 (x86_64)"

What I was doing when the application crashed:
When switching default window decorator to Compiz from control panel - during the 'preview' phase sends a segfault.

This happens every time the window decorator loads
