-- Information about the crash:
- What I was doing when the application crashed: 

Sometimes after wake from suspend PowerDevil crashes. Only happends when in a wayland session, not on X session. Does not happend all the time, but maybe 2 out of 3 times.

* Plasma 5.11.1 with Wayland session

The crash can be reproduced sometimes.
