Sentry Crash Report:

Description Sandro Mathys 2015-06-12 03:53:25 UTC 
Application: plasmashell (5.3.1)

Qt Version: 5.4.2
Operating System: Linux 4.0.4-303.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
It seems(!) that the crash happens either:
- When plugging in an external monitor (after having been suspended?)
- When plugging out an external monitor (before being suspended?)
- When plugging out (or in?) an external monitor _while_ being suspended

By suspend, I mean suspend-to-RAM (aka sleep aka not hibernate).

Note, that functionality of the desktop doesn't seem impaired - I wouldn't even notice there was a crash if the popup didn't tell me. So this is probably not very critical.

Sorry for opening a new bug - it seems there might be duplicates, but I can't tell well enough myself and didn't want to cause unnecessary confusion in another bug.

-- Backtrace:
