Description MScattolin 2024-08-01 16:44:27 UTC 
Stack trace at the end, this happens on a desktop computer where the display can be individually powered off.
the crash, according to dr konqi, happens after the specified amount of inactivity time set on powerdevil's kcm, where the computer is idle and the monitor is powered off.

I can't really reproduce it every time, but this happened to me around 4 times in about a week

STEPS TO REPRODUCE
1. Turn off the display
2. Let the computer idling until the "Turn off screen" time has been reached

OBSERVED RESULT
Powerdevil crashes
