Navigating away from /buddylist/X/buddies/recent causes SQL error

When navigating away from the my buddies recent posts page (/buddylist/X/buddies/recent) to any other page the following error message occurs.

user warning: Unknown table 'n' in field list query: SELECT DISTINCT(n.nid) FROM node WHERE status = 1 AND uid IN (1,4,7,9) ORDER BY nid DESC in /home/httpd/vhosts/webcommunicatie.org/subdomains/founder/httpdocs/includes/database.mysql.inc on line 167.

I have no idea how that is possible or where that query is generated yet.

other modules installed that might interfere => og, views 1.5 (but the previous views module had the same problem)
