OpenID with blog URL does not work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to login to SourceForge of Slashdot with http://blog.mithis.net/
2. End up at the following URL http://blog.mithis.net/?
openidserver=1&openid.mode=checkid_setup&openid.identity=http://blog.mithis
.net/&openid.claimed_id=http://blog.mithis.net/&openid.assoc_handle={HMAC-
SHA1}{4b3af8e2}{EEIygQ%3D%3D}&openid.return_to=https://sourceforge.net/acco
unt/openid_verify.php&openid.trust_root=https://sourceforge.net&openid.ns.s
reg=http://openid.net/extensions/sreg/1.1&openid.sreg.optional=nickname,ema
il,fullname,country,language,timezone&openid.sreg.policy_url=http://p.sf.ne
t/sourceforge/privacy
rather then the OpenID server request page.

What is the expected output? What do you see instead?

 You get the OpenID server page.

What version of the product are you using? On what operating system?
 3.3.2

Please provide any additional information below.

The tests at http://openidenabled.com/resources/openid-test/ seem to think 
OpenID 
works.

But using http://blog.mithis.net/archives/author/mithro URL gives "There was an 
error 
using your OpenID." on SourceForge and "Invalid identity supplied." on 
Slashdot.org.
