I get different errors/assertions with CVS of things, mostly related to GLib's
type system being slightly unsafe with regard to class refs. I've committed
these:

        * gst-libs/gst/audio/gstbaseaudiosink.c:
          (gst_base_audio_sink_class_init):

        * gst/volume/gstvolume.c: (plugin_init):
          Work around missing bits of thread-safety on older GLibs some
          more to avoid assertions when starting up multiple playbin
          objects concurrently (see #512382).

to -base and -bad respectively. This fixes all issues I've been seeing so far.
Now it either plays, or errors out with 'Error: Could not open resource for
writing.' or crashes gdb itself in mysterious ways (no idea what that is
about).

Any chance you could try with CVS? If yes, and you still have problems,
backtraces from G_DEBUG=fatal_warnings would be great.
