That's a URL created by the admin for view on site functionality. It's
hooked up to the contenttypes shortcut view, see:
http://code.djangoproject.com/browser/django/trunk/django/contrib/admin/sites.py#L234
The referenced shortcut view is here:
http://code.djangoproject.com/browser/django/tags/releases/1.2.5/django/contrib/contenttypes/views.py?rev=15639#L6

Not entirely sure (this is not an area of the code I've ever looked at) but
I'd guess it's due to the malarkey in that shortcut view having to do with
figuring out what site the object may be on.
