Alpha 4 Sub Page error

Alpha 4 Sub Page error

I just upgraded one of my apps from Alpha 3 to Alpha 4.  I have one page that is a list page with a series of links. Each link goes to a subpage.  In Alpha 3 clicking on one of the links from page xyz correctly goes to xyz#subpage.  In Alpha 4 this seems to be taking me to xyzsubpage#subpage.  That is, it is inserting the name of the subpage before the hash AND after the hash. This causes the app to break.  Is this peculiar to my app or are others seeing this as well?
