* attachment from comment #2 is a different issue (from the original
description) and one that I cannot solve without having the certificate(s) or
the URL from where I can fetch them.

* the warning from comment #3 will occurs if you do not trust the root
certificates that has signed the SSL certificate used by the web site you're
trying to access. 

The later can be normal since, by default, Mono does not trust any root CA.
It's up to you to install them - see the security FAQ on Mono's wiki for
instructions (look for mozroots) or my latest blog entries on why this can be a
"bad idea"(tm) @ http://pages.infinit.net/ctech/20110324-0943.html

What I'm expecting from the --trace are the few lines before your
NullReferenceException (or ArgumentNullException from comment #2). They should
include the https URL being accessed. This will allow me to download and
analyze the certificate(s) of the web site(s) and see why it cannot be be
processed correctly.

note: maybe the tool is generating some log files files (e.g. on errors) that
could also provide the https URL that are causing your exceptions.
