stream goes broken when listening to some radio

[Antonio M]

If I tune to Radioswisspop ( http://www.radioswisspop.ch/it/webradio )
for example, stream goes broken after sometime (faster in Rhythmbox
than in Totem, but I cannot play for more than hour, many times about
15 minutes..)) and it is independent from quality of stream.
Any comment??? I suppose that it is dependent on some gstreamer
package, in M$Windows stream on same hardware is o.k....
