XRDS for launchpad users missing local id

The user profile pages (like https://launchpad.net/~bamuller for instance) have a X-XRDS-Location specified in a meta element. The resulting XRDS document (mine is found here, for instance: https://login.launchpad.net/+id/wBDcJtN/+xrds ) does not contain a LocalID element with the user's local id, as it should. This value should be the same as the link href used in the user's profile page for openid.delegate and openid2.local_id. For instance, my XRDS document currently has:
    <Service priority="0">
      <Type>http://specs.openid.net/auth/2.0/signon</Type>
      <URI>https://login.launchpad.net/+openid</URI>
    </Service>

When it should have:
    <Service priority="0">
      <Type>http://specs.openid.net/auth/2.0/signon</Type>
      <URI>https://login.launchpad.net/+openid</URI>
      <LocalID>https://login.launchpad.net/+id/wBDcJtN</LocalID>
    </Service>

When that LocalID is not given, the OpenID redirection URL is crafted with the wrong openid.identity, and you get the error reported at https://bugs.launchpad.net/launchpad/+bug/451619 .
