Whenever connecting to a specific audio stream [1] as a rhythmbox backend, gvfsd-http stalls. The stream in question always launches by sending the radio station's indentification jingle, followed by the actual live stream. gvfsd-http stalls right after the jingle stops, when the live stream should start. Once that has happened, trying a different radio sation's audio stream fails as well. The only way to make it possible to listen to another stream at all is by rebooting the host; merely exitign the GNOME session and performing a GDM logon won't suffice.
