What is the problem?
Trying to access Special:NewFiles on beta, I see:
MWException from line 148 of /srv/mediawiki/php-master/includes/FormOptions.php: Invalid option newbies
I am assuming that, after T220447 was merged yesterday, this line in NewFilesPager.php needs to be changed.
Steps to reproduce problem
