Sorry, I got that wrong. Where in admin panel exactly?

Maybe something like this? Untested code:

function remove_title_attr( $nav )
{
return $nav = preg_replace('/href=\"(.*?)\"/', 'href=\"#\"', $nav );
}

add_filter( 'wp_nav_menu', 'remove_title_attre' );
add_filter( 'wp_page_menu', 'remove_title_attr' );
add_filter( 'wp_list_categories', 'remove_title_attr' );
