If DBUS_SESSION_BUS_ADDRESS is not set, trying to access the session bus will autolaunch a new bus. Autolaunching doesn't work without X11. We could check whether DBUS_SESSION_BUS_ADDRESS is set and launch the bus manually from Pulseaudio, but then clients probably wouldn't find the session bus, since the appropriate DBUS_SESSION_BUS_ADDRESS environment variable would only be defined within the Pulseaudio process. It would be nice if also the non-X11 sessions would set up the session bus already at login time, but I guess we can't rely on that. I'd expect the user bus work to solve this problem eventually, but until that becomes ubiquitous, I think putting module-dbus-protocol inside a .nofail section would be the best workaround. -- Tanu
