[GoogleCodeExporter]

This occurs in the 2005-Example project when I attempt to register a new user 
on a 
server with invalid certificate (even though SSL is not required):

Last call:    jc.Register(new JID(jc.User, jc.Server, null));

Error:
System.Reflection.TargetInvocationException was unhandled
  Message="Exception has been thrown by the target of an invocation."

Forgot to post the inner-exception:

Message:
"Object reference not set to an instance of an object."

Stack:

data)

Please create a new issue, rather than commenting on this one.  Just checked in

I'm going to close this issue, since people are continually confused by my 
directions NOT to add comments 
here, but to create new issues instead.
