Reproducible: Always

Steps to Reproduce:
run ktorrent til it backgrounds itself. then run it again to get the gui.

This problem happens with only the background running.

Actual Results:  
crash. see gdb output from ktorrent above.

Expected Results:  
Not a crash, that's for sure.

If you have beta code or need more info, I'm here to help you.

THANKS!
