Bug 288870

Application: systemsettings (1.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Moved 'KDE Test Language' from available to preferred.
Moved it up to the top of list: crash

Also if moving the top entry (Danish) down so x-test should have been the top one produces a crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemindstillinger (systemsettings), signal: Segmentation fault
