Description frank 2020-07-09 12:11:54 UTC 
Application: plasmashell (5.19.2)

Qt Version: 5.15.0
Frameworks Version: 5.71.0
Operating System: Linux 5.7.7-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Plasma randomly shows me crash reports at startup and exhibits some odd behavior
- Unusual behavior I noticed:
One of my screens shows a black background and the right click menu will not appear, at random. Often restarting the session will fix it.

The crash can be reproduced sometimes.

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

Comment 1 David Edmundson 2020-07-09 22:12:19 UTC 
So we have two bugs:


One a crash after we're already exiting in some dataengine code, which arguably we should fix.


but we shouldn't be already exiting randomly midway through things, which is the more important issue. That's coming from inside Nvidia code"

We can't do too much with that.
