It seems gnutls fails because the (client) certificate it uses for
authentication it doesn't support signing (and TLS client certificates
must support it).

Check (with certtool -i) if the client certificate contains the
following lines:

	Key Usage (critical):
		Digital signature.

(the one I used for testing contained them).
