KDE Platform Version: 4.10.1
Qt Version: 4.8.2
Operating System: Linux 3.2.0-40-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

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

I were changing my system time

- Unusual behavior I noticed:

System unexpectedly changes system time to UTC

The crash can be reproduced every time.

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