post indexer error

Publish a post or updating it gives me an error, when post indexer is installed. Haven’t seen it before installing this plugin. Although seems like the post gets indexed and published.

Error:

WordPress database error Incorrect datetime value: '1254091340' for column 'term_count_updated' at row 2 for query UPDATE wp_term_counts SET term_count = term_count + 1,term_count_updated = '1254091340' WHERE ( (term_id = '12' AND term_count_type = 'blog_lang_sv_se') OR (term_id = '16' AND term_count_type = 'blog_lang_sv_se') OR (term_id = '12' AND term_count_type = 'all') OR (term_id = '16' AND term_count_type = 'all') ) 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
