I guess, this may have to do with new version of php (5.4) http://mark-story.com/posts/view/new-errors-in-php-5-4

May be somewhere quiz may pass non-array types to drupal_render(&$elements). I am just guessing. Iwill take a look at this weekend, if i get a chance.

We are using 7.x-4.0-alpha with postgreSQL and PHP 5.4 and this fix worked great for us as well.

Hope we see it in the next release.
