Emacs expects just hostname and port in `url-proxy-services'. Generally the 
http_proxy environment variable will be prefixed with "http://";, as that is 
what some other programs expect.

Either change the above to explicitly use your proxy server details

    (setq url-proxy-services
          (("http" . "proxy-host:port")
;; etc...
          ))

or if you really want to use the environment variables, add some code to strip 
off the leading "http://"; and any trailing "/".
