Sentry Crash Report:

Description Thomas Ruch 2020-10-17 23:44:54 UTC 
Application: plasmashell (5.18.5)

Qt Version: 5.13.2
Frameworks Version: 5.73.0
Operating System: Linux 5.8.11-100.fc31.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 31 (Thirty One)

-- Information about the crash:
- What I was doing when the application crashed:
Right click on the thermal monitor plugin, select "Configure Thermal Monitor..."  Crash.  1 in 10 times or so, it will load the setting screen.  It's interactive for 5-10 seconds, then crashes plasma.

- Unusual behavior I noticed:
I saw a ghost window overlay at the bottom of the screen post-crash. It was about 75% transparent, and the window wrapped from the right side of the monitor to the left.  When I fired up the crash reporter, it disappeared and I was left with my normal desktop wallpaper.

- Custom settings of the application:
Nothing special.  Just running the Breeze-Dark-Noir theme.  Also crashes with the standard Breeze and Breeze-Dark, so I don't think it's theme related.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
