[pulseaudio-discuss] [PATCH] daemon: Initialize dbus to use thread-safe mode by default

[David Henningsson]

In most cases, we use dbuus from more than one thread, as we
e g enable real-time scheduling from the ALSA threads.
Therefore set dbus to thread-safe mode by default, as recommended
in https://bugs.freedesktop.org/show_bug.cgi?id=47060#c5

This fixes a bug where PulseAudio could crash in two parallel
calls to pa_make_realtime.
