Thanks Shyam,
Just did a nosy there.
GDB points to a problem when fetching the metadata property from the Beatbox
MPRIS implementation.
I implemented the MPRIS backend in Vala therefore the sound service simply
calling <beatbox-handle>.Metadata causes this GLib serialisation exception.
I took a quick look on D-feet and could not see any difference between
the MPRIS interface of Banshee and Beatbox. More interestingly d-feet is
able query this property no problem. I just queried it and it returned
without any complaints with :
{u'mpris:artUrl':
u'file:///media/ronoc_portable/music_library/intr_17/intr017_amute.jpg',
u'mpris:trackid': u'1',
u'sesam:genre': [u'Electronic'],
u'xesam:album': u'The Sea Horse Limbo',
u'xesam:artist': [u'aMute'],
u'xesam:title': u'The Floating Boat'}
This points to a Vala serialisation issue ... and not a problem with
Beatbox.
