Doesn't handle directory structure

Hi,
Liquid doesn't seem to handle overlapping names of directory structures and nodes. I just made up that way of describing this bug, so let me give you the example that I had problems with.

1) create page wiki/main_page
2) attempt to create page wiki/main_page/test ***fails*** Just brings you to wiki/main_page
(If main_page did not already exist, I would have no trouble creating main_page/test. It is only when a wiki node of the same title is present that there is a problem)
3) create page wiki/test
4) move page wiki/test to wiki/main_page/test
5) attempt to navigate to wiki/main_page/test ***fails** Just brings you to wiki/main_page
The node actually gets created, and when I navigate under the admin menus, I can go to the page. It seems that the lookup function of the wiki is not working.
