HTTP 404- ERROR when click on the navigation link (tree)

[DH]

Well, first off, don't know how to describe it correctly. 

I click on the products category and go into the product detailed page, there is the navigation tree on the head showed as

Home>Hand Tools>Nice Saw

everything is OK by here. However,when I want to go to the upper directory by clicking on "Hand Tools" which is in the center of the above navigation tree, it link to a HTTP 404 Error page!

Unlike directly clicking on the products category of "Hand Tools", which will show the link to

http://127.0.0.1/joomla/index.php?page=shop.browse&category_id=1&option=com_virtuemart&Itemid=1

,this navigation tree will link to

http://127.0.0.1/joomla/joomla/index.php?page=shop.browse&category_id=1&option=com_virtuemart&Itemid=1&option=com_virtuemart&Itemid=1

instead!

Is it a bug?

This problem exists when I try Joomla RC,RC2,even now RC3 with VM1.1 many nightly build versions even on nightly build version # 999.

Confirmed. Something has changed in Joomla again.
