 With the solution to solve the problem in file: class-wp-hooks.php

 {{{#!php
 public function apply_filters( $value, $args ) {
     ...
     foreach ( $this->callbacks[ $priority ] as $the_ ) {

         // Check if callable function or method exists.
         if ( !is_callable( $the_['function'] ) ) continue;

         ....
     }
 }}}
