[Radiant] fully qualified url's in admin interface

[Erik Ordway]

So I have a couple sites running Radiant .5.x and I have upgraded one  
of them to .6.3 and created another for something else.  They are  
running on an W2K3 (yes I know), mongrel,  and IIS with ISAPI-rewrite  
to proxy(Oh dear he really is crazy)  but I have replicated this  
problem on FreeBSD and Apache.

The public parts of the sites are fine and I can get to the admin  
pages but all the links to edit/create/so user the URL base that  
mongrel is running as and giving fully qualified urls like "http:// 
amago:5013/admin/page/edit/1"  when the url should be "/admin/page/ 
edit/1"  so that the urls can be proxied.

Is this the expected behavior.   It was was not under .5.x .  Any  
thoughs?  It seems like the " page_new_url(:parent_id => page)" are  
using routes create the url's and for some reason they are coming  
back a fully qualified and not relative like the links to images on  
those pages.

I think that have done something wrong but I have no idea where to  
start.
