Upgrade to 2.1 RC didn’t go so well..

WordPress database error: [You have an error in your SQL syntax near ‘.* FROM wp_posts LEFT JOIN wp_post2cat ON (wp_posts.ID = wp_post2cat.post_id) L’ 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) LEFT JOIN wp_categories ON (wp_post2cat.category_id = wp_categories.cat_ID) WHERE 1=1 AND category_id IN (5) AND (post_type = ‘post’ AND (post_status = ‘publish’ OR post_status = ‘private’)) GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 1

WordPress database error: [You have an error in your SQL syntax near ‘()’ at line 1]
SELECT FOUND_ROWS()

Anybody know why this error is happening?
