this bug i get frequently on different machines (all xp pro, latest patch stage). If i listen to a station (doesn't matter what format [mp3, ogg, ...]) and switch to another station without stopping the current stream (stop button) the whole app hangs with "closing feeds" and nothing happens. I have to kill it in the task manager. No error report just a frozen application.
This happens sometimes and sometimes not. Can't see what causing it.
In this case i switched from "canal7" to "you digg?":
