Need variable validation in nav-menu-template.php

[rpayne7264]

Getting the following on a site, while using RDP Wiki-Press Embed plugin in 'Wordpress Page' mode, which creates a non-existent dummy page to display scraped wiki content:

Warning: in_array() expects parameter 2 to be array, null given in nav-menu-template.php on line 607

Hi Robert,

This is an issue with the RDP Wiki-Press Embed plugin. I'd suggest visiting that plugin's ​support forums and re-asking your question there.

No, this is not an issue with my plugin. It is an issue of sloppy, non-defensive coding in the WP core files. There needs to be a check that $queried_object->ancestors is an array, before calling the is_array() function. Or, the $queried_object code needs to be refactored to ensure an empty array is returned, instead of null.

Fair enough. This is a duplicate of #24548.
