The first argument should be an array in acidfree.module on line 1962

Using Drupal-4.7.2
Acidfree-cvs /* $Id: acidfree.module,v 1.91 2006/07/07 20:08:10 vhmauery Exp $ */
filemanager-cvs // $Id: filemanager.module,v 1.15 2006/04/20 07:20:07 chx Exp $

I did not need to run the MySQL scripts in both Acidfree and filemanager, as these magically appeared in SQL for me (wow).

I get this error message
warning: array_keys(): The first argument should be an array in /home/katsheel/public_html/modules/acidfree/acidfree.module on line 1962.

when I create an acidfree album

Do I need to patch filemanager?
I've looked through the other posts and it seems there is a similar issue here
http://drupal.org/node/69153

but his error is on line 1966.
