unable to log in with my OpenID

I'm trying to log in with my OpenID (namely http://develop7.info), but am getting weird error message which says
{{{
return_to does not match return URL. Expected u'https://bitbucket.org/account/signin/complete/', got u'https://bitbucket.org/account/signin/complete/?next=%2F&janrain_nonce=2010-05-22T13%3A21%3A12Z9C9Pbq'\\
