Error in wp error-log with post indexer

Hello,
When I activate the post indexer I start receiving an error in the wordpress error log:

[14-Jul-2011 09:39:54] 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 ')' at line 1 for query UPDATE wp_term_counts SET term_count = term_count + 1,term_count_updated = '2011-07-14 09:39:54' WHERE ( ) made by edit_post, wp_update_post, wp_insert_post, do_action, call_user_func_array, post_indexer_post_insert_update, post_indexer_post_terms_insert_update

When updating a post/page..
I've found this thread

anybody knows if it's still a working solution?
thanks
