Application: plasmashell (5.4.2)

Qt Version: 5.5.1
Operating System: Linux 3.16.7-24-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
	When I started up my computer, already preconfigured with 3 monitors (2 external and 1 laptop) the loading screen seemed to acknowledge each of them.  Then when plasma loaded, it only showed backgrounds on 2 event though all 3 are set up for backgrounds.  The mouse is still visible if I drag it over the black screen however.  In order to get all the screens to work appropriately, I have to go to the system settings and disable and reenable the black monitor.  Then plasma crashes with this report and the screens return to normal.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
