STEPS TO REPRODUCE
1. run kdesu -u otheruser dbus-launch konsole
2. run dolphin from the console
3. let the screen sleep
4. wait for a few hours (can't reproduce it without a significant delay)
5. awake the screen by moving the mouse or using keyboard

OBSERVED RESULT

Dolphin crashes, but konsole doesn't crash

EXPECTED RESULT

No crash
