I'm getting this error when viewing a node in the form 'node/3'

user warning: Unknown column 'n.nid' in 'on clause' query: SELECT property FROM rdfcck_fields INNER JOIN node_access na ON na.nid = n.nid WHERE (na.grant_view >= 1 AND ((na.gid = 0 AND na.realm = 'all') OR (na.gid = 1 AND na.realm = 'workflow_access') OR (na.gid = 0 AND na.realm = 'workflow_access_owner'))) AND ( type_name = 'blog' AND field_name = 'field_blog_images') in /sites/all/modules/contrib/rdfcck/rdfcck.module on line 246.

If I go to 'node/3/rdf' I see the RDF code
