Package: pipewire
Version: 0.3.38-2
Severity: normal
X-Debbugs-Cc: kilobyte at angband.pl
Hi!
Upon startup, pipewire crashes for me. After poking around, it turns out
it's not the startup of pipewire itself, but pipewire-media-session connects
to the main part soon after.
The crash is easily reproducible by starting pipewire manually, then trying
to start pipewire-media-session as well.

Suspecting that you've implemented autostart only for systemd, I've tried it
first; I haven't checked yet if this crash is a systemd related problem.
(I'm at the mDebConf Regensburg -- so if any of pipewire maintainers is
here, feel free to take a look.)
