Rygel crashes when Audacious is launched

[Gavin Hamill <gdh acentral co uk>]

It was news to me, but Winamp-style music player Audacious has gained
MPRIS2 support in recent versions, including the one in Ubuntu 12.04.

I only know this because Rygel crashed as soon as I launched Audacious
for the first time today.

It is completely repeatable and happens with Rygel 0.14.0, 0.14.2,
Audacious 3.4.1 and 3.4.4:

gdh@gdh-x60s:~$ gdb rygel

Being able to 'beam' music from a DLNA client to Audacious, would be...
dare I say it.. audacious? 

Cheers,
Gavin.
