Drupal 5.1 + G2: Download Item URL Rewrite Problem

I'm using Drupal 5.1 with the Gallery Module (http://drupal.org/project/gallery) for integration. Everything works fine except the URL Rewrite rules for the "Download Item".

Instead of having:
http://www.example.com/gallery/d/151-1/filename.jpg
I get:
http://www.example.com/gallery2/gallery/d/151-1/filename.jpg

I tried playing with the URL Rewrite rules basically.
I tried playing with base_url too.

I've also noticed that while the link is:
http://www.example.com/gallery2/gallery/d/151-1/filename.jpg

that this would also work:
http://www.example.com/anythinghere/gallery/d/151-1/filename.jpg

So I think that the problem resides in some URL generation class instead of an .htaccess problem.

All other URL Rewrites seems to work.

Thanks!
