Copying this to the list in case someone else is having the same problem. The solution was to replace the application in the Preferences, Music tab to point to a music player that he had installed instead of xmms. I substituted Totem and it worked fine.

I substituted atunes (which is on my computer) and it launched and it 
works great!  Thanks for the tip.

Don't know why it would not work with GNOME MPlayer or Rhythmbox.  Maybe 
I didn't have exactly the right command...?

There is a non canonical xmms2 client player called Abraca.
