 Using other taxonomies since WP 2.3 in
 [http://wordpress.org/extend/plugins/xili-dictionary/ plugin xili-
 dictionary] , I just discover that now (since WP. 3.0) when deleting a
 term of his taxonomy, ''a menu item can disappear''. [[BR]]
 '''In which conditions ?''' When the term (i.e. news) is shared by
 taxonomy category and the plugin taxonomy named dictionary ? [[BR]]
 After deep tests (thanks to the night when time changes from summer to
 winter time), I can also reproduce it in current conditions : when a term
 is shared between taxonomies category and post_tag : If you delete the tag
 (i.e my test), if a category 'my test' exists and was active inside a
 navigation menu : the nav menu item disappear (unpleasant)- . [[BR]]
 [[BR]]
 The cause of this unexpected erasing, was the action hook ''delete_term''
 at end of '''wp_delete_term''' function and precisely the default filter
 ''_wp_delete_tax_menu_item''.
 The add_action in default-filter.php (line 233) don't pass the 3
 parameters and the function (menu-nav.php line 700) don't verify if it is
 possible to delete the menu item (as well done for term in other
 taxonomies in wp_delete_term itself) by testing the params and the
 taxonomy of the menu item content.[[BR]]
 [[BR]]
 Today workaround in plugins using new taxonomies : remove filter before
 deleting a term on concerned taxonomies and add it after. [[BR]]

 Hope that explanations were explicit.

 Best regards
