Application: systemsettings (1.0)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.1
Operating System: Linux 2.6.35-ARCH i686

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

If I use "single-click to open files and folders" setting for my mouse and double click on "Date & Time", systemsettings crashes. But if I use "double-click to open files and folders" and double click on "Date & Time" it works.

I saw a report about a situation like this but it says the bug is fixed.

- Distribution method:
I installed KDE from a snapshot repo: http://arch.morrigan.ch/kde-snapshots/os/i686/

The crash can be reproduced some of the time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
