Description Vishnu 2017-12-26 05:49:05 UTC 
Application: plasmashell (5.11.4)

Qt Version: 5.10.0
Frameworks Version: 5.41.0
Operating System: Linux 4.14.6-1-ARTIX x86_64
Distribution (Platform): Archlinux Packages

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

I had a Konsole terminal in fullscreen opened, and then I pressed the Super key (which is my shortcut to Application launcher). The launcher comes up, and with in a few seconds, crashes along with plasma.

- Unusual behavior I noticed:

The screen flickers as though gamma changes and is reset to normal.

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".
