Redirect to custom url when registration fails?

When I want to redirect the user after successful registration, I just use “registration_redirect” filter hook. How about when registration fails, which filter hook should I use? I looked into wp-login.php but I didn’t see any filter/action hook that I could use. How do I go about this?

You could add an htaccess redirect or try out the theme my login plugin: http://wordpress.org/extend/plugins/theme-my-login/. It has options for custom redirection.
