Sentry Crash Report:

Description le.trmr 2015-08-16 12:01:58 UTC 
Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.5-1-ck x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Changing displays (external connected) with the associated hotkey (FN + F7).
This happens around once a change cycle (press hotkey until you are back at the first setting)

- Unusual behavior I noticed:
"Taskbar" vanishes and reappears.
Sometimes one screen stays black, while only the mouse will be visible there.

- Remarks:
Acceleration set to UXA.

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".
