Bug 321678

Application: systemsettings (1.0)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

System settings crashes after activating "Get New Effect" in desktop effects. 
Every time, also after a restart. I just upgraded to kde-runtime etc. 4.10.4 via debian experimental.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
