Blogger / Bloglines RSS Problems?

I'm seeing some weirdness with Bloglines and some of my RSS feeds from blogs hosted on Blogger. Several people seem to have switched from the old atom feeds like http://blogname.blogspot.com/atom.xml?bsuser=blogname to http://blogname.blogspot.com/feeds/posts/default. The former now returns a 404 and the latter doesn't seem to work in Bloglines. I've tried hitting the URL directly and it returns the RSS XML. I also tried Google Reader and it seems to handle the new URL just fine as well (same company, so one would hope it would work).

So why the hell doesn't Bloglines show the new feeds even when I remove the old subscription and add the new one? And why can't this shit redirect on its own?
