Gstreamer module problems

[josh]

After installing the gstreamer0.8-mad and gstreamer-mad-0.6.4-5 debs to
try and get mp3 playback on rhythmbox, I get a recurring error message;

Failed to create the player: Couldn't initialise scheduler. Did you run
gst-register?

gst-register0.6 and gst-register0.8 execute without a problem, showing
the gstreamer-mad module has been included, but the problem persists. I
can run rhythmbox/any gstreamer app as root, but playback still fails.
(Could not open resource for writing/Could not pause playback)

Any help would be appreciated,
