Application: plasmashell (5.25.5)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.15.0-48-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
I was logged in, then locked the account, switched to another user account, and then used that for a while. Then, switched back to the original session. On unlock, plasma shell crashed and the taskbar disappeared (alt-tab worked while it was restarting). After maybe 10-15 seconds, Plasma restarted and everything went back to normal.

The reporter is unsure if this crash is reproducible.

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