 When testing 5.0 beta 1 on an existing error-free installation, I started
 seeing fatal errors in the logs of a multisite network I maintain.

 To quickly duplicate, install and activate the
 [https://wordpress.org/plugins/wp-user-profiles/ WP User Profiles plugin]
 (which uses meta-boxes for user profile pages) and visit your profile
 inside of WordPress admin.

 {{{
 PHP message: PHP Fatal error:  Uncaught Error: Cannot use object of type
 WP_User as array in /public/wordpress/wp-admin/includes/template.php:1066
 }}}

 Specifically:
 {{{
 thrown in /public/wordpress/wp-admin/includes/template.php on line 1066"
 while reading upstream, client: 184.58.156.205, server: , request: "GET
 /wp-admin/users.php?page=profile HTTP/1.0", upstream:
 "fastcgi://unix:/var/run/php/php7.2-fpm.sock:", host: "jjj.blog",
 referrer: "https://jjj.blog/wp-admin/users.php?page=account"
 }}}


 In short, it is incorrect to assume that meta-boxes are always for posts,
 and that the `args` key is always present, and is an array. (The
 `is_array( $box['args'] )` check from 2016, r37913, supports this notion.)

 Related to #45112, and r43608.

 Patch with a recommended fix imminent.
