Summary says it all. I can't play internet radio, either nothing happens or the Rhythmbox window freezes so that it must be killed.

Same stream plays perfectly in VLC and other players.

I suspect that this bug may be connected to gvfsd-http, because this process usually is very small and needs around 0% CPU time, but when trying to use Rhythmbox to play radio, its memory usage grows and it uses 1-2% CPU time (on a 1,6 GHz Atom processor)

Here is a debug log, starting at that point where I have selected a radio station from the list and pressed the Play button:
