I had the same problem... and found a possible fixed on bugzilla. See http://bugzilla-test.gnome.org/show_bug.cgi?id=151307 comment #13.
try as root>
prelink /usr/lib/libdbus*so*
worked for me, but xmms won't launch after it (I did try and install mp3 drivers for it)
PS. Please let us know if it works for you
