[Plugin: Media Library Categories] Fix for Bug from 6/7/2011 11:02:46 by sean

Add

add_action('delete_post', 'mc_delete_post_relations');
function mc_delete_post_relations($pID) {
    wp_delete_object_term_relationships($pID, 'media_category');
}

to the media-categories.php end. works fine for me.
