Bug 372878

Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.10-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Attaching my T460s to a dock the second time crashes plasma.

- Unusual behavior I noticed:
It flickers heavely.
Input is only received from the laptop not periferals from the dock.

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