Application: plasmashell (5.8.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:

I've opened my laptop, entered my password. And in the systemtray i had a message informing me about a crash. 

Everything seems to work as expected. 

Yesterday, a few hours before I've closed the laptop, another plasma-session crashed (this happens frequently). I've restarted it from a konsole with 
kquitapp plasmashell && kstart plasmashell
as usual.

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