Hi,
I checked it out and there seems to be an issue with Googles feed
fetcher (Gadgets API version) and the rss version of your feed (I am
getting the same error on all the gadgets using it). I had no problem
with the Atom version though. >>

To clarify, you should use http as that is what the fetcher is looking
for. Also, I had no problems with your rss feed using my other
fetchers/parsers that use Googles AJAX Feed API instead and I have
been planning to switch these gadgets over to use that instead as I
personally find it more stable and reliable. (they are migrating the
Gadget API with OpenSocial)
As a check, you can test your feeds here using the load feed by url.
