I noticed you're using nsd 3.4.2... 3.3ad13 is recommended. You can get it <a href=http://www.arsdigita.com/acs-repository/one-version?version_id=2081>here</a>. I haven't tried it but I'm guessing 3.4 loads its config differently somehow and isn't seeing the definition of UsersTableContainsConvertedUsersP.
