Sentry Crash Report:

Description burritobazooka+kde 2020-09-28 00:33:08 UTC 
Application: plasmashell (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-10-amd64 x86_64
Distribution: SolydXK

-- Information about the crash:
- What I was doing when the application crashed: 
I removed the 'panon' third-party plasmoid from the panel because its audio buffer was lagging behind what I was hearing. I then clicked on the Weather Widget and after about 4 seconds, plasma crashed and restarted (the Weather Widget behaved as expected before that)

- Unusual behavior I noticed:
panon audio buffer was lagging behind what I was hearing (although today is the first time I've tried this addon)

- Custom settings of the application:
panon is: https://store.kde.org/p/1326546 - I used the widest frequency range at about 25fps
weather widget is: https://store.kde.org/p/998917
I have three screens and both of these were on my third screen.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
