I had a similar problem.  The key thing to know is
that using $c->response->redirect is just setting the
HTTP headers for you, it isn't telling Catalyst to
stop everything right there and then and process the
response.  So your default end action is trying to
process a template, but isn't finding one.  You need
to either manually detect the redirect request in your
end action and have it skip forwarding to the template
toolkit view or use something like the Renderview
action:

http://search.cpan.org/~mramberg/Catalyst-Action-RenderView-0.04/lib/Catalyst/Action/RenderView.pm

which will do that for you.

If you look at the source code for that action you
will gain a better understanding.
