Description of problem:

rhythmbox crashes with the following on the console:

** (rhythmbox:3845): CRITICAL **: file dparammanager.c: line 319
(gst_dpman_attach_dparam): assertion `G_PARAM_SPEC_VALUE_TYPE
(dpwrap->param_spec) == GST_DPARAM_TYPE(dparam)' failed
rhythmbox: pcm_plug.c:882: snd_pcm_plug_hw_params: Assertion `err >= 0'
failed.
                                                                        
       
(gnome_segv:3852): Gtk-WARNING **: Ignoring the separator setting

after a audio file is chosen and the play button is clicked.

Steps to reproduce the crash:
1.  open rhythmbox
2.  import directory of audio files
3.  select any file and click play button

Expected Results:
I would expect the song to play.

How often does this happen?
Every time.

Additional Information:
XMMS plays the same audio files in the same location perfectly if the
ALSA output is selected.
Playing audio files within nautilus does not work either.
Sound for quake3 does not work (as reported in bug 117744 at
bugzilla.redhat.com ... see that bug for full lspci and lsmod of my
system)
