 If setting object terms and one has not type casted string 0 to integer 0
 then term_exists will see this as a category name and return false, the
 category 0 does not exists and wp_set_object_terms will create it.

 It exists on line 1452 of taxonomy.php
 (http://core.trac.wordpress.org/browser/tags/3.2/wp-
 includes/taxonomy.php#L1452)

 The fix is simple, switching is_int to is_numeric
