Bug 306873

Application: kcmshell4 ()
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic i686
Distribution: Ubuntu 12.04.1 LTS

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

Changing the panel clock time zone resulted in the user time zone being set wrong, then the panel clock failed to update using NTP and crashed.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
