Well, I fixed the problem moving the "if" that instances "result" even though it getting HTTPError into the "try".

------------------------------------------------------
        # send the data
        try:
            result = urlopen(request)
            status = result.getcode()
            reason = result.msg
            if self.show_response:
                self.announce('-'*75, result.read(), '-'*75)
        except socket.error, e:
            self.announce(str(e), log.ERROR)
            return
        except HTTPError, e:
            status = e.code
            reason = e.msg

        if status == 200:
            self.announce('Server response (%s): %s' % (status, reason),
                          log.INFO)
        else:
            self.announce('Upload failed (%s): %s' % (status, reason),
                          log.ERROR)

-------------------------------------------------

So now it explains the real error:
