Application: kcmshell4 (4.10.3)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-25-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
This happens when I try to set the clock to get the time automatically from any time server. I guess it is related to the iMac where Kubuntu is installed on, since it did not happen in the years before, when I used an Intel laptop for Kubuntu. Also setting the timezone does not get any desired result (display the right time it does not). When I set the time manually, it is wrong again after reboot.

The crash can be reproduced every time.
