I've customized my site in such a way that the breadcrumb urls at the top of category/subcategory/product pages are incorrect. By default, these are .../home.php?.... , and it seems they come from the $location variable. I can't really grasp what's happening in location.tpl beyond the first few lines.

How can I set this variable? How can I change the underlying breadcrumb links?

thanks
