Category Depth Issue/Error

[chadderuski]

Using 1.3.9h with default template (although not a full clean install). Only 1 installed language.

I am getting a "blank page" in the store front while testing a very deep category tree.
Note that I am not getting any php errors, and that I can navigate the tree properly in zencart admin.

Path in admin:

Categories / Products - DEEP > ONE > TWO > THREE > FOUR > FIVE > SIX > SEVEN > EIGHT > NINE > TEN > ELEVEN > TWELVE (with 1 product)

Store Front url at depth TEN:

/index.php?main_page=index&cPath=687_688_689_690_691_692_693_694_696_697_698

If I attempt one more click down (to category level ELEVEN), I get the empty page. There is no mixing of products/categories.
This is a just a deep path to 1 product. Product also shows up in search, but clicking product also generates a blank page without any php errors.

However, if I "hack" the url to:
index.php?main_page=product_info&cPath=700&products_id=7348

I can see the product at that depth (cPath=700 is category "Twelve") without the full path showing in url or breadcrumbs....

Any advice on where to look would be much appreciated. My thoughts are that something is going awry during breadcrumb generation...

Ideas?

PS: Yes, I know this is not practical for a store front. However, I am rewriting much easypopulate code and have modified it to allow 'unlimited' multi-lingual categories with images and metatags. This issue showed up while testing the code on a deep category chain. I cleared the chain I imported and regenerated within the admin with same results.

I just test on a clean 139d and 139h install and they do work correctly...
