 Since r32806, I'm seeing this in my customizer:

 {{{
 Notice: Undefined property: stdClass::$fallback_cb in /srv/www/wordpress-
 develop/src/wp-includes/nav-menu-template.php on line 311
 }}}

 Using a pretty standard approach to menus:
 {{{
 wp_nav_menu( array(
         'theme_location' => 'primary',
         'container'      => false,
         'menu_class'     => 'nav navbar-nav',
         'walker'         => new Bootstrap_Nav_Menu(),
         'fallback_cb'    => '' // @todo
 ) );
 }}}

 This worked without a debug notice previous to r32806.
