Podcasts don't download if the files are all the same filename.

I noticed a podcast that wouldn't download correctly in Rhythmbox. They appear different, but each one was the exact same episode! I thought it was a problem at the server-side, but then I opened the feed in Firefox and found that Firefox could download the different episodes. Then I noticed the filename, and each and every filename had the same name, but in a different folder. I think this is why Rhythmbox wasn't updating, it looked and it saw was the "same filename, same filename" without looking at the folder part of the url. I'm pretty sure this is a bug in Rhythmbox.
