Description Dashon 2020-02-27 21:49:10 UTC 
Application: plasmashell (5.17.5)
 (Compiled from sources)
Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.5.5-200.fc31.x86_64 x86_64
Distribution: Fedora 31 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
I was using the alphablack widget to change the transparency of the desktop widgets.
I removed the widget from the desktop. Then I immediately decided I didn't like it and added the widget back using the widget menu shortcut alt+d, a. 

- Unusual behavior I noticed:
The screen went black for about 2 seconds and then I was alerted to the crash.

The crash does not seem to be reproducible.

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