Comment 3 for bug 597324

You didn't specify the URL to which to go ("2. go to this url"). I tried both 'https://launchpad.net/+openid-callback' and the really long one (with a nonce!) and, unsurprisingly, got "Your login was unsuccessful: Invalid openid.mode: '<No mode set>'". This seems very reasonable to me--why would someone go to the +openid-callback page unless they are in the middle of an openid dance? It also does not match your description of the bug.

I'm afraid I still do not understand your report.
