Sentry Crash Report:

Description Jamie 2016-05-30 04:42:05 UTC 
Application: plasmashell (5.6.4)

Qt Version: 5.5.1
Frameworks Version: 5.22.0
Operating System: Linux 4.4.0-23-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Trying to move the panel to the correct screen
- Unusual behavior I noticed:
The panel is stuck on the wrong screen that is not the primary display. Closing it and trying to add to a different screen still goes to the wrong display.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
