Bug 322638

Application: kcmshell4 (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.9.9-302.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

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

I noticed that my clock was wrong. It had somehow gotten set to UTC --- I have no idea how or when. The crash occurred when I tried to set the time zone back to New York Eastern. I don't know if the time zone having gotten reset to UTC is directly related to the crash or not.

- Unusual behavior I noticed:

Authorization error?

The crash can be reproduced every time.

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