Bug 346996

Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 4.0.1-1.ge3a374a-desktop x86_64
Distribution: "openSUSE 20150425 (Tumbleweed) (x86_64)"

-- Information about the crash:
Prerequisites:
1. Plug- in a new display into laptop.
2. Setup it via "Display Configuration" as an only display.

How to reproduce:
1. Take a sleeping laptor with disconnected display.
2. Plug-in a display.
3. Turn laptop on without opening the lid.

The trick with a closed lid is not always necessary. Sometimes the same crash happens while pluging in another display at run-time.

The crash can be reproduced sometimes.

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