Bug 340004

Probably it is not krunner specific. Krunner crashed when I changed display config in systemsettings. This is crash BT:

Application: krunner (krunner), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Reproducible: Sometimes

Steps to Reproduce:
1.go to system settings
2.change screen config (I'm in a multihead setup)


Actual Results:  
3. krunner and kwin crashed.

Expected Results:  
3. no crashes
