Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
My second monitor worked perfectly with OpenSuse 13.2, but in Leap 42.1, it becomes inconsistent when I try to set the second desktop to the left of my laptop's one, crashing eventually.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
