-- Information about the crash:
- What I was doing when the application crashed:
Since Iswitched from pulseaudio to pipewire a few months ago, plasma sometimes
crashes when switching users (both users run plasma on X11). Users are *not* in
the audio group.
Hypothesis is that it's crashing because unlike pulseaudio, pipewire does more
aggressive device adding/removing on user switch.
There are a few other long fixed plasma crashes regarding device
adding/removing but this one still happens on up to date plasma.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
