Bug 372734

Application: plasmashell (5.8.3)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.8-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

I tried to change the layout between my laptop and the external monitor: switching between mirrored screens, extended desktop or only external monitor display. Setting the last one is possible but the morkspace crashes and plasma has to restart (first, only the background picture appears). It does it automatically.

Plasma version : 5.8.3 (Archlinux distro)
My desktop setting: layout is desktop (not folder view)
Graphic card : Intel Ivybridge Mobile (2013)
Firmware : Mesa DRI Intel(R) Ivybridge Mobile
Session with X

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
