Application: plasmashell (5.8.3)
 (Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-ck-r1 x86_64
Distribution: "Gentoo Base System release 2.3"

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

I closed lid of my laptop for few hours, opened again later.
Plasmashell was not running on open.
The last time it restarted automatically but I usually I have to alt+f2+plasmashell to restart it.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
