Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
The KDE time management module crashes consistently when time is changed manually or if the settings is switched from manual to automatic via ntp servers. 
- Custom settings of the application:

The crash can be reproduced every time.

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