IRC problems with Tor

[Grozdan]

Hello,

I recently started using Tor and Privoxy on Linux and so far everything is 
working like it should. However I'm having one small problem. Whenever I try 
to connect to irc.freenode.org port 6667, I always get the below message

-leguin.freenode.net- *** Banned:  Tor freenode is hidden-service-only 
(mejokbp2brhw4omd.onion) - see freenode.net/irc_servers.shtml.
[error] Closing Link: 127.0.0.1 (Banned)

I then went to the freenode site and looked up information on how to make 
freenode work with Tor. In the documentation, it said to add the below line 
to my torrc file - http://freenode.net/irc_servers.shtml#tor

mapaddress  10.40.40.40  mejokbp2brhw4omd.onion

and then to restart Tor, which I did. But I keep getting the same response 
from freenode and it doesn't allow me to connect at all.

I'm using Konversation as IRC client on KDE. Konversation itself doesn't have 
proxy settings, but instead uses the global proxy settings of KDE. My KDE is 
configured to use privoxy/tor for its connections and it works without a 
problem. I also tried another IRC client (XChat) but I get the same response 
from freenode. Does anyone know how to resolve this problem?

Thanks in advance
