[X2Go-User] Mac OS X client and ssh-agent?

Are others seeing the behavior I am? I have an open x2go session running and leave my computer for a while. When I return, the session has timed out and I get the dialog asking if I want to close it.

But, when I close it and try to re-open a new session, it fails to connect.

Only after I go to a terminal shell and kill the ssh-agent process does it re-connect. I am using password authentication, and it works fine after stopping ssh-agent. Is there some setting I have wrong?
