webchat 4.0.0 source code

I am having a problem with webchat and openfire. I get an error in the logs

"WARNING: Error joining room:

No response from server.: "

This only happens when certain characters are entered in the name field in the webchat

For example. The following characters will cause a chat to fail: "¸"

I need to source code so i can debug the problem.

I am trying to checkout the webchat source code for version 4.0.0 .

I have gone to http://svn.igniterealtime.org/svn/repos/fastpath/webchat/ but the only code available is that on trunk. Both branch and tag folders are blank. How can I get the version I need?

Also I had a look at the jars in the .war file at /WEB-INF/lib/ and need to know what version smack and smackx are used here?
