Hi,
I am seeing a problems with a new set up environment using the broker with SSH tunneling and session autologin. I start x2goclient connecting to my broker, log in, receive a list of session profiles, select the one that uses auto login, enter my SSH proxy password and get asked to enter a password for some key.
Authentication to the broker is no problem:

After entering the SSH Proxy password auth.log says
-- Mar 24 13:52:43 access sshd[24551]: Accepted password for x2gosshproxy from 80.187.108.145 port 8948 ssh2 Mar 24 13:52:43 access sshd[24551]: pam_unix(sshd:session): session opened for user x2gosshproxy by (uid=0)
so that worked, too!
On the x2goserver, I see this in auth.log right after I entered the proxy password:
-- Mar 24 17:49:31 termsrv sshd[10065]: Did not receive identification string from 10.173.20.3 Mar 24 17:49:31 termsrv sshd[10067]: Did not receive identification string from 10.173.20.3
10.173.20.3 is the inner IP address of my ssh proxy and x2go broker. I think this is where the problem lies. I assume at this point x2gobroker should connect to x2goserver using the x2gobroker account and the installed public key. Manually, I can create this connection from the broker though:
-- root@access:~# su - x2gobroker x2gobroker@access:~$ ssh 10.173.20.2 Welcome to Ubuntu 13.10 (GNU/Linux 3.11.0-12-generic x86_64)

Anybody with good troubleshooting skills? :D
