Description Wian Potgieter 2019-12-11 08:51:30 UTC 
Application: plasmashell (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.0.0-37-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
I resumed the laptop from suspend.  I tried to turn down the volume by using the FN+F2 key.  I then tried to turn down the volume using the KMix system tray entry.
- Unusual behavior I noticed:
When using the FN+F2 hot-key, the frame of the volume OSD drew without any content.

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

New crash information added by DrKonqi

plasmashell (5.17.4) using Qt 5.13.2

- What I was doing when the application crashed:
Resumed KDE after unplugging my PC from the work monitors and plugging into home monitors.
Clicked on  the NetworkManager System tray entry and plasmashell crashed.

- Unusual behavior I noticed:
Desktop had difficulty switching layouts to the changed (but known) screen setup.  Screens were switched around.

-- Backtrace (Reduced):
