PHP error after update WP to 3.6 (debug true)

After update WordPress WP to 3.6 I’ve got an php error

“Strict Standards: Declaration of lctwidget_Taxonomy_Dropdown_Walker::start_el() should be compatible with Walker::start_el(&$output, $object, $depth = 0, $args = Array, $current_object_id = 0) in (..)\wp-content\plugins\list-custom-taxonomy-widget\list-custom-taxonomy-widget.php on line 300”

I have turn on DEBUG mode, after disable debug error disappear.

I tested it, and after change line 288 from:
function start_el( &$output, $term, $depth, $args ) {
to
function start_el( &$output, $term, $depth = 0, $args = array(), $current_object_id = 0 ) {

Everything works ??
Maye this tip help someone.
