Bug 386166

Application: org_kde_powerdevil ()

Qt Version: 5.9.2
Frameworks Version: 5.39.0
Operating System: Linux 4.13.7-1-macbook x86_64
Distribution: "Arch Linux"

-- 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.

-- Backtrace:
Application: org_kde_powerdevil (org_kde_powerdevil), signal: Segmentation fault
