sql error

Ran into a problem on a custom page module I wrote + taxonomy block, where taxonomy block wasn't returning any tids, so was having an sql query error.

I patched taxonomy_block to have a sizeof($tids) check before the sql query and rendering the block...

query: SELECT DISTINCT(n.nid), n.title, n.body FROM term_node t INNER JOIN node n ON t.nid = n.nid WHERE t.tid IN () AND n.status = 1 ORDER BY sticky DESC, created DESC LIMIT 8 in /var/www/domains/p/post.thing.net/public_html/drupal-4.6.0/includes/database.mysql.inc on line 66.

you will find the patch inline, and the custom module I was having the problem with attached.
