URL escaping in paths is broken.

We don't seem to be handling URL-escaping correctly. I got different results trying to access the subscribe URL without a password.

wget http://192.168.1.101/v0/subscribe → 401 Unauthorized
wget http://192.168.1.101/v%30/subscribe → 404 Not Found

The two commands should have returned the same thing.

This seems to work fine in a browser, since the browser automatically canonicalizes the URL.
