Application: kcmshell4 ()
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-35-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: 
Noticed the clock is constantly behind, so adjusting time-zone and time-server.

- Unusual behavior I noticed: 
Application crashes when clicking apply or ok-button, after adjusting the settings.

- Custom settings of the application:
Amsterdam time-zone. Clock correct after crash/re-start of application, but next reboot of computer the clock is again approx. 1 hour behind.

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