Comment(by arma):

 Actually! I think this might be Tor's fault, yes?

 Here's what the wikipedia socks page says:
 {{{
 For username/password authentication the client's authentication request
 is

     field 1: version number, 1 byte (must be 0x01)
     field 2: username length, 1 byte
     field 3: username
     field 4: password length, 1 byte
     field 5: password

 Server response for username/password authentication:

     field 1: version, 1 byte
     field 2: status code, 1 byte.
         0x00 = success
         any other value = failure, connection must be closed
 }}}

 We get "version number, 1 byte (must be 0x01)" on the request from pidgin,
 and then we use version 5 in our response. But don't we want to use
 version 1 in our response? It's not the socks version, it's the auth
 format version.
