-- Information about the crash:
When I play music via the Strawberry music player, plasmashell sometimes
completely crashes and restarts. Some notable details:
1. This happens once per boot maximum (sometimes it does not happen). After
plasmashell recovers, I can listen to music as normal.
2. I have PlasMus Toolbar widget active on my app panel. I suspect there might
be something there, given the stack trace shows plasma widgets/addons as well
as pipewire.
I've disabled scrolling text and lyrics display for PlasMus Toolbar -- I'm
wondering if somehow that was the cause, but I can't be sure. Hopefully this
stack trace makes more sense to you than me.
The crash can be reproduced sometimes.
