Application: plasmashell (5.5.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.13-5-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
First I made a System upgrade via DVD from openSUSE 13.2 x64 to openSUSE LEAP 42.1 x 64. The upgrade was done without any problems and I tryed, after the last reboot do modify the mini programs. Suddenly plasmashell crashs. Online search with google dosn't give matching results.

The crash can be reproduced every time.

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