Description Jean Antelme 2020-09-19 17:01:13 UTC 
Application: plasmashell (5.19.5)

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.19

-- Information about the crash:
- What I was doing when the application crashed: I just wanted to  open an application but not even that panel appears any more.

- Unusual behavior I noticed: This ihas been happening ever since the last major update to 20.4 and now all my video players crash on opening. I can't watch a video any more.
 What should I do?

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Bus error
