I have a similar issue using this version of torsocks with irssi to connect to Freenode's hidden service. In the irssi window, I receive the error:
"Tor is not an HTTP proxy" and the following is in my /var/log/tor/notices.log: Sep 21 17:28:38.000 [warn] Your application (using socks4 to port 80) is giving Tor only an IP address. Applications that do DNS resolves themselves may leak information. Consider using Socks4A (e.g. via privoxy or socat) instead. For more information, please see https://wiki.torproject.org/TheOnionRouter/TorFAQ#SOCKSAndDNS. Sep 21 17:33:28.000 [warn] Socks version 67 not recognized. (Tor is not an http proxy.)
