Application: plasmashell (5.12.4)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-112-generic x86_64
Distribution: Ubuntu 18.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was just mousing over the Google Chrome item which had 4 browser windows open. It's never crashed before but this time instead of popping up a 4 panel list above the launcher it either showed up a blank area or nothing and the lanucher crashed.

The crash does not seem to be reproducible.

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