Looks to me like they're not accepting OpenID 1.x Compatibility mode. That's weird because they send a 1.x link in response to the request for an application/xrds+xml document: 

GET / HTTP/1.0
Host: username.blogspot.com
User-Agent: Drupal (+http://drupal.org/)
Content-Length: 0
Accept: application/xrds+xml

HTTP/1.0 200 OK

So they are actually telling us to use an OpenID 1.x protocol, then complaining when we do. If you change the openid.ns parameter of the URL where the error occurs (Drupal's redirection) to openid.ns=http%3A%2F%2Fspec.openid.net%2Fauth%2F2.0 then it takes you to a properly handled error page.

This is a bug in Blogger's implementation. Please log a bug report with them.

More than that - a patch is available, but nobody cares. http://drupal.org/node/233885
