Restful Routes Malfunction

My rails application is working correctly for everything except one

In development on my local machine it all works fine, but when deployed
to the production environment, the 'new' form is mis-routed when
submitted. Instead of calling the 'create' action as it should it goes
directly to the 'index' action and the 'create' is never called.

The form in question is a photo upload form. The generated form tag is:

<form action="/photos" class="new_photo" enctype="multipart/form-data"
id="new_photo" method="post">

The routes as shown by 'rake routes' are:

                    photos GET /photos
{:controller=>"photos", :action=>"index"}
formatted_photos GET /photos.:format {:controller=>"photos",
                             POST /photos
{:controller=>"photos", :action=>"create"}
                             POST /photos.:format
{:controller=>"photos", :action=>"create"}

The production log shows that right after the 'new' action the next
action is the 'index' action.

All of this works in development, other very similar controllers that
don't have the enctype="multipart/form-data" (that is just normal text
forms) work just fine, the behavior is the same on different browsers.
The production environment is fastcgi, while the development environment
is a standard mongrel. Both are Rails 2.0.2.

So, My question is Why do this not work? Why does this one form go to
the GET action when it should go to the POST action?

Any help or suggestions would be appreciated.
