I just wanted to go ahead and post this here in case someone else comes searching for it.

Gallery 3.x does not work properly with PHP 5.3 and Zend Loader. This is easily address by moving Gallery's php.ini file to your public_html directory. Gallery's default php.ini file does not have any configuration to load the Zend Loader so Gallery will then work without issue. If you see any date.timezone errors you may need to add that setting to the php.ini file as well. By default we use:

Code:
date.timezone="America/Chicago"
If you have any issues with this please feel free to submit a ticket.
