Customization Question

Here is my setup:
WordPress Install
Wordpress is installed in the /wordpress directory of my site. /wordpress/index.php is my blog page.
Site Header/Footers:
I have a header.php and a footer.php in the root of my site. These files provide the basic site layout and personalization for multiple domains, including site menu content. The main content cell uses a PHP Include statement to include my /wordpress/index.php file. I just display posts with this file, I do not include other content such as archives or links in this page.
The layout above has worked fine for months, and continues to work. However, I am trying to make some changes and am beating my head on the wall.
I am trying to use the Links functionality as part of my left side navigation bar – on all pages of the site, not just on the pages I have blog entries on. Here is what I am doing:
1. ) In my /header.php, I include the following code:
top of page:

<?php require($abs_path.”/wordpress/wp-blog-header.php”);?>

left navigation cell:

<div class=”secondarynav”><?php get_links_list(‘order’,hide_if_empty); ?></div>

This worls fine on all pages on my site – except Gallery. Whenever I try to visit a page in my Gallery subdir I get the following error:
Fatal error: Call to a member function on a non-object in /home/brianbur/public_html/wordpress/wp-includes/wp-l10n.php on line 37
Any thoughts?
