Comment (by dmchale):

 +1 for this patch. We do not have WP_DEBUG enabled anywhere, but noticed
 some of our sites never automatically updated to 4.2.3 - upon
 investigating, we found this PHP warning littering the error_log. Logging
 into the admin area and clicking to upgrade successfully worked, however.

 As kitchin said, the php docs definitely mention the possibility of this
 issue on some systems, per the "Note" blockquote under Return Values. For
 the most broad system compatability, you can't simply trust a glob()
 inside a foreach() [http://php.net/manual/en/function.glob.php]
