Favorites appearing in breadcrumb of favorited resource

Steps:

1) I went to Advanced Search.
2) I chose "Text" for the Media Type.
3) I clicked on the result "SHOPPING WITH ADDITION AND SUBTRACTION!!" This should target http://www.curriki.org/xwiki/bin/view/Coll_phil19355/SHOPPINGWITHADDITIONANDSUBTRACTION.
4) I was shown the resource with a breadcrumb of "Untitiled" indicating the devil's handiwork, but it was actually inside another member's Favorites collection with no indication anywhere in the Revision History that the devil was involved.

The bug is that the breadcrumb is reflecting a parent of another member's Favorites, which is not supposed to occur. The URL shows correctly, until you click on the parent in the breadcrumb, then it shows http://www.curriki.org/xwiki/bin/view/Coll_phil19355/SHOPPINGWITHADDITIONANDSUBTRACTION?bc=;Coll_wllmgrady.Favorites.

See the screenshot.

This is just weird and bad.

We need to make sure you can't see another member's favorites as the parent in a breadcrumb.
