Bug 280495

Application: systemsettings (1.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

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

I selected the "Set date and time automatically" check box in the Date and Time dialog, then clicked "Apply."  After the crash, when opening the dialog, the option was set.  I unchecked it and clicked Apply.  Then re-checked it at clicked Apply, and it crashed again.  I was able to duplicate the crash three or more times in a row... however, as I write this, I was unable to crash it again.

The crash can be reproduced every time.

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