hello, I have the same issue with totem and banshee(gstreamer), 

the stream is: http://cluster.quantumart.ru/broadcast/default.aspx?media=rusradio

error message in terminal:

however it works on opensuse 11, totem and banshee are able to play the stream(gstreamer backend) 

workaround:
vlc on hardy and on intrepid is able to play the stream.

it is so boring that banshee and totem are not able to play such a stream on ubuntu interpid 8.10 and hardy 8.04 :-(
