Duplicate key error

Hi,

When I want the following urls point to the same url and put them in the FUP store I get an error (manually)

http://www.domain.be/Default.aspx?tabid=130 and http://www.domain.be/Path/Pagename.aspx (both the same url)
and I want to point them to http://www.domain.be/shor...h/Otherpagename.aspx
I get an error (see below)

So when I change a page title 2 or more times the older urls won't exist anymore or the new won't be added to the database?
