I cannot understand why this chain shouldn't be validated... What was
the reason for the test? It is now accepted because the verification
procedure detects the same certificate being verified and trusted and
thus considers it ok.

As a side-effect I noticed that that gnutls_x509_crt_verify() behaves
different than gnutls_x509_crt_list_verify() - i.e. no date checks,
which shouldn't occur.
