Sentry Crash Report:

Description Connor Meredith 2018-11-27 18:57:00 UTC 
Application: plasmashell (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I had recently plugged in a Logitech C920 webcam, which comes with a microphone. The microphone was not working, and someone said in their case, the microphone was muted. I clicked on the volume control in my taskbar (all of this is while the webcam is attached via USB) and then the taskbar and my desktop disappeared. However, I was still able to use ALT+F2 to use the konsole, open programs, reboot, etc.
- Unusual behavior I noticed:
My taskbar and desktop disappeared. When I say the taskbar disappeared, I mean it was simply no longer present. Programs appeared like they were in fullscreen.
When I say the desktop disappeared, I mean that the desktop was suddenly a blank gray screen with no folders/widgets/etc. Programs (e.g., Chrome) were still functioning, however.

The crash can be reproduced every time.

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