[Plugin: Simple Tags] Updating of tags count field on term_taxonomy table fails when update a page

fresh install of wordpress 2.8.4 and only simple-tags plugin and situation is the same. Can someone confirm this bug?

fresh install of wordpress 2.8 and only simple-tags 1.6.6 plugin and don’t works 🙁

commenting lines 17,21 and 22 of wp-includes/taxonomy.php solve the problem.

original code (wp-includes/taxonomy.php):

function create_initial_taxonomies() {
    register_taxonomy( 'category', 'post', array('hierarchical' => true, 'update_count_callback' => '_update_post_term_count', 'label' => __('Categories'), 'query_var' => false, 'rewrite' => false) ) ;
    register_taxonomy( 'post_tag', 'post', array('hierarchical' => false, 'update_count_callback' => '_update_post_term_count', 'label' => __('Post Tags'), 'query_var' => false, 'rewrite' => false) ) ;
    register_taxonomy( 'link_category', 'link', array('hierarchical' => false, 'label' => __('Categories'), 'query_var' => false, 'rewrite' => false) ) ;
}
add_action( 'init', 'create_initial_taxonomies', 0 ); // highest priority

modified code (wp-includes/taxonomy.php):

//function create_initial_taxonomies() {
    register_taxonomy( 'category', 'post', array('hierarchical' => true, 'update_count_callback' => '_update_post_term_count', 'label' => __('Categories'), 'query_var' => false, 'rewrite' => false) ) ;
    register_taxonomy( 'post_tag', 'post', array('hierarchical' => false, 'update_count_callback' => '_update_post_term_count', 'label' => __('Post Tags'), 'query_var' => false, 'rewrite' => false) ) ;
    register_taxonomy( 'link_category', 'link', array('hierarchical' => false, 'label' => __('Categories'), 'query_var' => false, 'rewrite' => false) ) ;
//}
//add_action( 'init', 'create_initial_taxonomies', 0 ); // highest priority
