Unknown column 'f.tid' in 'where clause'

I have just clean-installed drupal cvs. I've created a vocabulary with one term and assigned it to forums. When viewing http://drupal/index.php?q=forum I get following message:

user error: Unknown column 'tid' in 'field list'
query: SELECT tid, count(*) AS c FROM history h, node n, forum f WHERE f.nid = n.nid AND n.nid = h.nid AND n.type = 'forum' AND n.status = 1 AND h.uid = '1' GROUP BY tid in d:develdrupalincludesdatabase.mysql.inc on line 69.

When viewing the contents of the forum I get two:

user error: Unknown column 'f.tid' in 'where clause'
query: SELECT COUNT(DISTINCT(n.nid)) FROM node n, term_node r LEFT JOIN forum f ON n.nid = f.nid WHERE n.nid = r.nid AND ( (r.tid = '5' AND f.shadow = 1) OR f.tid = '5' ) AND n.status = 1 AND n.type = 'forum' in d:develdrupalincludesdatabase.mysql.inc on line 69.
