-- Information about the crash:
Strange bug in the icons-only task manager, which causes the shell to crash in
very particular circumstances
1. Have Firefox running with multiple windows, another app running with
multiple windows, and another app which is pinned but not running
2. Hover over Firefox to show the window previews
3. Move the cursor directly (don't pass over other app icons) to the pinned
unstarted app (you can move the mouse over the window previews if this makes it
easier to reach the pinned app)
4. From there, move the mouse onto another app with multiple windows
5. Plasma shell will crash at this point
This is very reliably reproducible using Firefox as the first app. On a
different machine (which admittedly I've hacked on), VSCode can cause the same
behaviour, but I've not been able to reproduce this elsewhere or with other
apps.
The crash can be reproduced every time.
