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. Start some applications (Firefox, Steam, Ghidra, VSCode, etc)
2. Lock the session
3.  Unlock the session

OBSERVED RESULT
Some apps (Firefox, Ghidra, VSCode) are force closed instantly, discarding various data, and a plasmashell crash report notification pops up on screen.  Some apps (Steam, Konsole, Yakuake, Krusader) survive the crash and don't lose any data.

EXPECTED RESULT
No apps close, and no plasmashell crash popup appears.
