Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.13-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

The laptop was suspended using 2 external screens while the internal screen was disabled. Later it was resumed, but without external screens, only the laptop screen was active. Plasmashell crashed immediately after login.
After the crash (or before crash, I do not know) the destop reset to the default one as described in comment 16 of bug #371734.

I suspect that bug #371734, bug #373569, bug #369537 and maybe bug #362812 are somehow connected to this problem.

The crash can be reproduced sometimes.

-- Backtrace:
