I guess I'm using the newer openssh, as I have ecdsa server keys in /etc/ssh.

First on the server I edited sshd.config and found all three keys were uncommented, so I commented out rsa and ecdsa, leaving only dsa.  Restarted the ssh server, and session manager on client machine, and tried new session but same error.  Then I renamed the two ecdsa keys, restarted again, but same error.

Why doesn't x2go support elliptic curve?  I'm using the one from Debian Testing (Wheezy):
