SQL statement as an error when trying to access system overview

There is an issue that is happening on one of our Movable Type installations, and I have absolutely no idea what could be. Looking into the databases, the needed data is there, so I am suspecting that there is an issue elsewhere. Please let me know if you have any idea what could be causing this issue.

SELECT COUNT *, extract(year from visitorstats_visitor_created_on), extract(month from visitorstats_visitor_created_on), extract(day from visitorstats_visitor_created_on) FROM mt_visitorstats_visitor, mt_permission WHERE (visitorstats_visitor_created_on >= ?) AND (permission_author_id = ?) AND (permission_blog_id = entry_blog_id) GROUP BY extract(year from visitorstats_visitor_created_on), extract(month from visitorstats_visitor_created_on), extract(day from visitorstats_visitor_created_on)

The issue appears to be happening in areas that the user does not have permissions to (for instance, a blog author trying to access the system overview panel). But this is an exceptionally ugly error message. Is this a normal message (some of our other sites have a higher version that doesnt do this)

Thanks for your help!
