Sentry Crash Report:

Description Ondrej.Bozek 2015-05-18 17:00:44 UTC 
Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I disconnected my NTB from docking station so, my external monitor disconnected
- Unusual behavior I noticed:
This error window appeared. 
Quiet often KD completely freezes with black screen, only solution is hard restart. It doesn't react to any input (keyboard, ctrl+alt+f1 console etc.). This happens almost always when I  disconnect monitr (dociking station). Sometimes it helps to connect my monitor back again.
Also I have trouble to set higher resolution when I switch monitor for one with higher res. It somehowe just keeps settings from old monitor and I can't force it to higher res.
All in all multimonitor setup still feel very buggy and needs thorough testing.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
