Classification: Plasma

Backtrace (core dump)
SUMMARY
Sometimes when I alt tab to some other app from a fullscreen game, it causes
plasma to crash. I think its due to the notifications that got suppressed
during the full screen game (due to DND) and now tries to show a notification
that X notifications were missed. Also it seems some app is asking for
attention (yellow) in the task manager too when this crash happens. So could be
a race condition.
It doesn't happen often (2 times in last month) but I thought I would report it
anyways. The issue can be closed if its deemed a one off condition or not
clear.
STEPS TO REPRODUCE
(I cannot reproduce it consistently)
0. (Icon Only) Task Manager is configured to Group tasks ("By Program Name")
1. Start some game in full screen (and wait for some time).
2. Wait for events that trigger notifications or cause an app to "Demand
Attention" (orange/bouncing icon in taskbar).
3. Alt tab out of the game to another running app (like the terminal).
OBSERVED RESULT
plasmashell crashes
EXPECTED RESULT
plasmashell doesn't crash
