Bug 490836

SUMMARY
After I lock the screen and the screen turns off (or if I'm idle and it locks the screen automatically), I get a KDE Power Management crash notification when I unlock the screen. It always happens after the screen turns off, but never when the screen only locks. Locking and unlocking the screen before it turns off doesn't crash anything.


STEPS TO REPRODUCE
1. Lock the screen manually or wait for it to lock automatically.
2. Wait until the monitor turns off.
3. Unlock the screen.

OBSERVED RESULT
After unlocking the screen, I get a notification saying that KDE Power Management has closed unexpectedly.

EXPECTED RESULT
Nothing should crash after unlocking the screen.
