Application: plasmashell (5.12.7)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-48-generic x86_64
Distribution: Ubuntu 18.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Clicked the network manager icon in the bottom menu and tried to connect to a WLAN

- Unusual behavior I noticed:
Background wallpaper went black for just half a second, then the crash report appeared. However, the WLAN connection was established.

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