It would be good to find out what the source of that key missing is instead of hiding the error.

In our case hook_default_page_manager_pages() contained $page->menu = ''; which caused this warning. Updating to $page->menu = array(); solved the problem.

Thanks @sjerdo. I'll close this as works as designed unless there is another reason that we can fix.
