Note that libssh versions from 0.5.3 onwards also support the group14-sha1 key exchange algorithm. Debian Wheezy is shipping 0.5.4, so that would be covered. Unless you need even older client to connect to the server (for instance Ubuntu Precise), I suggest removing "diffie-hellman-group1-sha1" from the KexAlgorithms key again, because "diffie-hellman-group14-sha1" - which is also in the list - should be enough to let X2Go Client (via libssh) connect to the server.
i can confirm that "diffie-hellman-group1-sha1" ist not necessary with older x2go clients and "diffie-hellman-group14-sha1" is enough. Thanks for the hint!
