Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.9.8-1.gaf90696-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was working in tty7 and returned to tty8. 

- Unusual behavior I noticed:
This happens when other programms are open and you work temporarily in an other useraccount. 
As soon as coming back with alt+ctrl+Fn in several occasions, that brings the house down. Plasma recovers apparently fast from this.
As I had unrecoverable crashes with sddm before I am using now lightdm as opposed to the normal distribution asset. 
This is a Lenovo X201 laptop with normal monitor setup, no external monitor or dockingstation attached during the events. 
Only "mixed" asset is the presence in Leap of Kontact version 4.

The crash can be reproduced sometimes.

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