there still seems to be a problem here, after all fixes and applying the patch i get:
Failed to save super.tlv.redhat.com: Mysql2::Error: Duplicate entry '_timestamp' for key 'index_fact_names_on_name': INSERT INTO `fact_names` (`created_at`, `name`, `updated_at`) VALUES ('2013-05-21 07:24:23', '_timestamp', '2013-05-21 07:24:23')
