Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.20-11-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Fresh restart after keyboard non-responsive during lock screen. Both have occured several times. I logged in over ssh and tried to shutdown but although the ssh session was inturrupted as expected the system did not restart. I proceeded to do a hard shutdown, then restarted after several seconds. On restart KDE crashed again. I've been running system from fresh OpenSuse Leap installation for approx 10 days, and this is the seventh such crash with the same progress cycle.

The crash can be reproduced every time.

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