Sentry Crash Report:

Description quantummhl 2018-12-14 12:35:22 UTC 
Application: plasmashell (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-12-generic x86_64
Distribution: Ubuntu 18.10

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

I was using my computer normally, writing some notes in notes application, when suddenly application stopped responding.
On other monitor I had my terminal opened and it was functionning nomally.
At that moment task manager was completely unresponsive, and I couldn't switch apps, etc.

- Unusual behavior I noticed:

I've stumbled upon this behaviour couple of times, so I use these two commands to reset plasma shell:
"kquitapp5 plasmashell"
"kstart5 plasmashell > /dev/null 2>&1 & disown"
But this time second command hanged and nothing happend. 
After a minute or so screen went completely blank.
I went to terminal screen ( ctrl + alt + F2 ) and tried this command but with same result.
After some time, everything went back to normal.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
