rhythmbox: failed to create spider element

[John Kodis]

I've tried to listen to an internet radiostation using rhythmbox, but
all that I can get to happen is for an error dialog saying "Failed to
create spider element; check your installation".  The error message is
sufficiently cryptic that I can't figure out what a spider element is,
why I would want one to be created, or what about my installation it
is that I should check.

Has anyone else had success with this?
