23130	nav_menu and custom taxonomies	dmikam		"I found out that in case when you have some custom taxonomies, their terms could has the same term_id. The case is when two(or more) terms with the same term_id but from different taxonomies are added to Nav Menu, and the user is in one of this terms - they are both marked like active in menu. 
This is because of lacking condition in _wp_menu_item_classes_by_context function in wp-includes/nav-menu-template.php file:


{{{
// if the menu item corresponds to the currently-queried post or taxonomy object
} elseif (
	$menu_item->object_id == $queried_object_id &&
	(
		( ! empty( $home_page_id ) && 'post_type' == $menu_item->type && $wp_query->is_home && $home_page_id == $menu_item->object_id ) ||
		( 'post_type' == $menu_item->type && $wp_query->is_singular ) ||
		( 'taxonomy' == $menu_item->type && ( $wp_query->is_category || $wp_query->is_tag || $wp_query->is_tax ))
	)
) {
}}}

but it needs to be like that:

{{{
// if the menu item corresponds to the currently-queried post or taxonomy object
} elseif (
	$menu_item->object_id == $queried_object_id &&
	(
		( ! empty( $home_page_id ) && 'post_type' == $menu_item->type && $wp_query->is_home && $home_page_id == $menu_item->object_id ) ||
		( 'post_type' == $menu_item->type && $wp_query->is_singular ) ||
		( 'taxonomy' == $menu_item->type && ( $wp_query->is_category || $wp_query->is_tag || $wp_query->is_tax )/*ADDED CODE-->*/ && $menu_item->object==$queried_object->taxonomy/* <--ADDED CODE*/)
	)
) {
}}}


I found this bug on 3.1.4 version, but looks like it still remains on the las version of wordpress.
