Comment (by charlestonsw):

 Just ran into the same issue on a WP Multisite upgrade.

 No Opcache or other caching of code running on my site.   I am using PHP 7
 and FPM though.

 Now sure how new code for about.php is executing before new code from
 i10n.php but it does seem to be a general problem.

 The error is transient.   The update appears to have worked pulling in the
 new code.  A simple site refresh cleared the problem but the question
 remains - how are some sites executing line 22 of about.php with the
 get_user_locale() call BEFORE the function is loaded from i10n.php?

 Don't want to be another "me too" +1 on this thread.  Trying to provide
 some clues to help isolate and resolve the issue.
