Application: plasmashell (5.23.3)

Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.13.0-21-generic x86_64
Windowing System: X11
Distribution: Ubuntu 21.10
DrKonqi: 5.23.3 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on one of the system tray icons when plasmashell crashed.

- Unusual behavior I noticed:
Plasmashell was rather slow. Note: I use an NVIDIA graphics card. Not using Wayland; X11.

The reporter is unsure if this crash is reproducible.

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