Application: systemsettings (1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-41-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: Try adjust kde clock, switching between server "europe.pool.ntp.org" or "pool.ntp.org", then the application system settings crash with error 6.
If I set manually, kde keep the right hour, but just until the next reboot.
- Unusual behavior I noticed:

The crash can be reproduced every time.

-- Backtrace:
Application: Impostazioni di sistema (systemsettings), signal: Segmentation fault
