That's just the result I expected. Object is a GSListener, a subclass of 
NSProxy, and our current code isn't able to extract the method signature 
from that kind. I still think the solution I suggested in the last mail, 
using -methodSignatureForSelector: is the correct one, but I would like 
to get comments, at least, from Richard and David on that.
