Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was setting up the object CPU charge. 

- Unusual behavior I noticed:
While trying to place the app, I accidentally touched the lower border of the screen with the taskbar running "automatic hide" .  As soon as you touch it, this crashes plasma. I signed this to the error that has 26 duplicates but konqui did not accept this (or does not work). I think  it is related.

- Custom settings of the application:
Task bar hiding automaticly, comes up if you touch lower screen end.

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