Hum, it may be sth else but it seems that both errors are related to
the code we provided for CRL and issuer check, which is untested with
the nss backend. We mainly took into account some comments sent by Rob.

As you might have noticed, building libcurl under Debian creates
libcurl*-openssl and libcurl*-nss versions but does not provide any
libcurl*-nss. Hence the lack of tests of our patches with nss.

Rob might be able to tell what we forgot. Sorry for the time you lost on
