Comment:

 Reproduced the notice if `plugins_api()` returns a `WP_Error`:
 {{{
 PHP Notice:  Undefined property: WP_Error::$compatibility in wp-includes
 /class-wp-error.php on line 78
 }}}
 We should probably check if `$info->compatibility` is set in `update-
 core.php`, like we do for `$info->tested`. See [attachment:29583.patch].
