Bug 470475

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Variably, though It usually happens the most in panel/desktop editing mode (right click on the panel, choose enter edit mode).
2. Add multiple addons (plasmoids) very quickly, then right-click and choose remove that plasmoids for all of them.
3. Several popups will show up, click to "x" to close all the popups.

OBSERVED RESULT
Plasmashell either freezes or crashes most of the times.

EXPECTED RESULT
The widgets/plasmoid remove completely popups should be closed, or the widgets should be added to the desktop

ADDITIONAL INFORMATION
Backtrace logs (first one I get from the coredump after it crashed), second time I tried to reproduce the bug by this guide through gdb: https://wiki.archlinux.org/title/Debugging/Getting_traces#Getting_the_trace , and it freezes when I adding new plasmoids after removing multiple of them (I used privatebin, it only save the logs for one month, so I tried paste.debian.net instead):
