SQL error after inserting an imagefield

Hi! I'm using CCK version 5.x-1.5, the permisssions of my "files" and "tmp"directories is 777, the download method is public, and the MySQL version is 5.0.38.

After I insert an imagefield in a content type, Drupal shows the following error message at every page displayed:

user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '> '1') ORDER BY ASC LIMIT 0, 3' at line 1 query: SELECT node.nid, value, node.title AS node_title, node.changed AS node_changed FROM node node WHERE (node.type IN ('audio','image','video','textos_curtos','textos_longos')) AND (.value > '1') ORDER BY ASC LIMIT 0, 3 in /var/www/testedrupal/includes/database.mysql.inc on line 172.

Drupal only stops displaying the above message after I disable the imagefield module.

Thanks in advance,
Carlos.
