Application: kcmshell4 (4.10.1)
KDE Platform Version: 4.10.1
Qt Version: 4.8.2
Operating System: Linux 3.2.0-38-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

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

I press "Apply" and short after "OK" after I havde made om changes.
The change does not seems to matter, as long you just "OK" with ind a 1-2 sec. efter you pressed "Apply"

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
