Google Toolbar released but I have a problem

I tried some of the functionality of the new Google Toolbar that has some cool new features but it seems like there are some problems. I created a button and the feeds show up in the drop-down as they should but when I click on any of the feeds it doesn't work. A dialog box comes up asking to connecto to www.blogger.com and if I press cancel the url is something like  https://www.blogger.com/atom/9019115/115409179283556611
I tried to use both the blogger atom feed as well as the feedburner feed.

If any of you have an idea what is going on please let me know. Click here to add the button I made.

Update. Thanks to a comment by Ionut Alex. Chitu it was solved. I converted the FeedBurner feed to RSS 2.0.
