Application: kcmshell4 (4.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.2
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 time/zone

- Unusual behavior I noticed:

NTP claiming it cannot connect to servers
not seeing anything in the system log
NTP time updated, but impossible to set the time zone except in the console by exporting TZ
HTTPS certifcation was failing as well until I manually updated the timezone

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