 When setting up the loop with query_posts, an SQL error is generated if an
 empty category is excluded. For example, if the category with the id 8 is
 empty, query_posts('cat=-8') produces:

 WordPress database error: [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 '8 AND (post_type = 'post' AND (post_status = 'publish' OR
 post_status = 'private' at line 1]
 SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts LEFT JOIN wp_post2cat
 ON (wp_posts.ID = wp_post2cat.post_id) WHERE 1=1 8 AND (post_type = 'post'
 AND (post_status = 'publish' OR post_status = 'private')) GROUP BY
 wp_posts.ID ORDER BY post_date DESC LIMIT 0, 10
