In addition, it appears that a fix for this is available upstream, linked in
that tracker entry. It would be nice if this fix could be made available in
Debian.
To have all the information in one place and not rely on Fedora: this
is https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/merge_requests/31
which fixes
https://gitlab.gnome.org/GNOME/libgnome-volume-control/-/issues/34.
I'm surprised that you're seeing this without using pipewire from
experimental - the upstream issue report implies that it's a
regression with newer pipewire? But your bug report seems to indicate
that you're using testing/unstable pipewire?
This is a bug in a "copylib" that is not packaged separately because
it has an unstable API/ABI (libgvc), so unfortunately it needs to be
fixed in multiple places.
For gnome-shell let's use the original bug #1126514.
[... some other packages ...]
Similar code (a fork) is present in cinnamon-desktop, although it
isn't *exactly* the same codebase. Cinnamon team: please check whether
Cinnamon also crashes when a Bluetooth headset is connected while
using Pipewire for audio; if it does, libcvc will likely need to pick
up changes from libgvc. I haven't cloned the bug for cinnamon in case
it's unaffected, I don't know how far away libcvc is forked.
Sorry, forgot to cc the Cinnamon team in the previous mail to this bug.
It looks like Cinnamon does have this issue too (there's an upstream bug
report), so I'm cloning the bug one more time.
