get_registered_nav_menus() is empty when its callad in the hook plugins_loaded

I’m trying to get the registered nav menus in my plugin. As I’m using Redux Framework, I’m inside the hook plugins_loaded. So the problem is the get_registered_nav_menus function returns an empty array.

This is the reduced case:

 function lmm_reduxbug($defaults = array()) {
      var_dump(get_registered_nav_menus());
 }

 add_action('plugins_loaded', 'lmm_reduxbug', 14);

Any idea?

Thanks in advance!
