What do you mean by "you're never hitting the GnuTLS code"?

I have been doing some more testing and compared behavior of the latest 
Emacs trunk on Debian (Squeeze) and Windows 7. I am using the same 
configuration in both instances:

(require 'smtpmail)
(setq send-mail-function 'smtpmail-send-it
      message-send-mail-function 'smtpmail-send-it
      smtpmail-starttls-credentials '(("smtp.gmail.com" 587 nil nil))
      smtpmail-auth-credentials (expand-file-name "~/.authinfo.gpg")
      smtpmail-default-smtp-server "smtp.gmail.com"
      smtpmail-smtp-server "smtp.gmail.com"
      smtpmail-smtp-service 587
      user-mail-address "address@hidden"
      smtpmail-debug-info t)

On Debian, at first, I didn't have `gnutls-bin' installed, so it failed 
with the same error as on Windows ("SMTP protocol error", see my earlier 
post). I then installed `gnutls-bin' and then everything worked fine.

On Windows, I noticed that it couldn't find `gnutls-cli' either so I 
added the directory with the executable to the Emacs path.

Now I get this:

Why is the behavior with the same configuration different on Windows 
than on GNU/Linux? For the record, I made sure that I am using the same 
GnuTLS version on Windows and GNU/Linux, v2.8.6.
