I don't see this bug anymore. Maybe since Frameworks 5.16.0.
Can someone confirm?

I'm on 5.5.4 + frameworks 5.18 and get this bug on git as well. To reproduce, right click the tray icon and open audio volume settings, and then do it again (close settings, click icon, open settings). First time works, second time segfaults plasmashell. Of note this crash only happens when audio is playing - ie, when the first tab the window opens has an audio bar in it that the plasmoid is going to read from pulseaudio. That seems to strongly indicate that these crashes have to do with asynchronous operations with the PA reader. I attached one of the useless Arch traces, and I could recompile plasmashell and plasma-pa with debinfo if it would help.

Created attachment 97077 [details]
Crash report without debinfo
