Bug 441394

Application: plasmashell (5.22.4)

Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.13.12-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to get back to work on a huge database development project (I have 40 tables to load w/ ~60gb of data--and thats my data dictionary!) and when I switched back to my "admin" desktop, which has a lot of plasmoids of dubious quality, to try and fix some problem w/ flakey behavior on the part of the Qt windows decorators which made it impossible to get Konsole out of my way.

I did have an active (proxyish) connection to Google Cloud SQL, and was also connected to MariaDB on my workstation.  A million Firefox pages open trying to figure out if I want to try and learn pgloader or take a bigger leap w/ openrefine...but memory was about 8 out of 16gb used.  I had been keeping an eye on things w/ HTOP, and I didn't see anything that looked like a memory leak.

I suspect it is a flakey plasmoid, and I am getting rid of them as soon as I...ah crap...it just crashed again just LOOKING at the plasmoids.

Tmux and framebuffer are looking pretty good these days....
- Unusual behavior I noticed:
Switching activities and it seems to be to the one cluttered w/ plasmoids.
- Custom settings of the application:
Nothing too odd.  I have just installed it, and am trying to work out the glitches (no sound?!?), so I have gone over my alternatives w/ a fine tooth comb to make sure that everythign Python3 is 3.8 (I did install 3.9 as well, as I figure if I am going to have to learn it, might as well start w/ the current version--now figuring out which verion of Qt (5.15? 6?) to use is a problem for another day.

The crash can be reproduced every time.
