Bug 313101

Application: kcmshell4 ()
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.7.1-030701-generic x86_64
Distribution: Ubuntu 12.10

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

I noticed with a newish install that the timezone the clock shows had changed to utc instead of my local (related to dual boot with windows possibly?), changed that, then got a crash.

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