Comment 8 for bug 269471

Ross, what feeds are you attempting to use. The reported URLs above were all from the abc.net.au podcasts feeds - I've looked through their feeds and they are, to varying degrees, non conforming to the standards for feeds. I think this may be the problem.

I've reported the problem to the ABC and they don't seem very much to care. If you are trying ABC feeds, you might want to add a complaint, if it's not the ABC, put the feed through http://feedvalidator.org/check.cgi and check whether it's the feed or rhythmbox.

(I'm using the same version as you and most feeds work).
