A self-signed cert's signature algorithm really isn't that
important.  You either trust that cert or you don't.  Which
is why openssl started to ignore this for root CAs.  I'm not
sure what gnutls does with it.

I think gnutls by default has a minimum size of 727 for the DH
size while openssl doesn't have any check for this.  But if you're
using DH you really want to move to something like 2048 if
