Sentry Crash Report:

Description T 2016-06-27 13:21:57 UTC 
Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-24-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Restaring a dual monitor from off with Nvidia 361.42

I noted the crash report happened after I have experienced the dual monitor fault, which I worked around by setting the wrong monitor.

- Unusual behavior I noticed:

Setting dual moniors is falkey, the condition changes as you go along, eg which monitor ends up as main monitor.

- Custom settings of the application:
Dual monitors

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".
