KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

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

Changing the NTP Server.

I believe that the issue is authentication.

The crash can be reproduced some of the time.

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