Here's an easy test case:

(open-network-stream
 "nntpd" (get-buffer-create "*foo*")
 "news.eternal-september.org" "nntp"
 :type 'starttls
 :end-of-command "^\\([2345]\\|[.]\\).*\n"
 :capability-command "HELP\r\n"
 :success "^3"
 :starttls-function
 (lambda (capabilities)
   (if (not (string-match "STARTTLS" capabilities))
       nil
     "STARTTLS\r\n")))

First of all, I think the error message is lacking.  It should say more
about what's failing.

As to the bug -- gnutls by default now refuses to deal with MD5
certificates.  We could override that, and instead let the network
security manager notify the user that the connection isn't safe.

I think that's a better solution, but others may differ.
