Can you have git be more verbose about what it's going?  If it is running
OpenSSH's ssh client, can you have it pass -v (verbose) a few times?  That
might provide more hints about what's going wrong.  You should also try
enabling Twisted logging in your SSH server to see if any useful information
is available there.
