Why is Django sending the wrong email template?

Question

I can not find the error in this code. I tried to isolate the problem, but it works when I copy the corresponding code to a separate file. The problem should be related to the surrounding code, but I do not see how relevant this is. Everybody is here:

The problem is with the message "Activate your PROJECT account". He sends me an email with something like this:

--===============1413769924==
Content-Type: text/plain; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable

text here

--===============1413769924==
Content-Type: text/html; charset="utf-8"
MIME-Version: 1.0
Content-Transfer-Encoding: quoted-printable

text here

Where the "text here" is the same for both versions of the email, but it is not in the actual files, not when I try to send emails from another script. Here is the code:

def join_transporter(request):
    form = TransporterJoinForm(request.POST)

    if request.POST and form.is_valid():
        user = User(
            username = form.username.val,
            first_name = form.first_name.val,
            last_name = form.last_name.val,
            email = form.email.val,
            is_active = False,
        )
        user.set_password(form.password1.val)
        user.save()

        Profile.objects.create(
            user = user,
            phone = form.phone.val,
            company_name = form.company_name.val,
            details = Transporter.objects.create(),
            address = Address.objects.create(
                city = form.address.city.val,
                province = form.address.province.val,
                country = form.address.country.val,
                street = form.address.street.val,
                postal_code = form.address.postal.val
            )
        )

        e = send_multipart_email('Activate Your PROJECT Account', 
            'emails/transporter_joined', 
            {'user':user, 'fee': settings.PROJECT_FEE * Decimal('100.00'),'settings':settings},
            [user.email],
            send_immediately=False
        )
        e.attach_file('/home/PROJECT/webapps/media/files/InsuranceLetter.pdf')
        e.send() # <------- PROBLEM IS HERE

        send_multipart_email('Transporter Joined', 
            'emails/staff_transporter_joined', 
            {'trans':user,'settings':settings},
            ['[e-mail]','[e-mail]']
        )
        messages.info(request, 'Thank you for registering. Please check your email for details on how to activate your account.')
        return redirect('home')

    if not isinstance(recipient_list, list): recipient_list = [recipient_list]

    d = {'settings':settings} # default context vars
    d.update(data_dict)
    c = Context(d)

    try:
        tt = loader.get_template(template+'.txt')

    if send_immediately:

FYI, I think I finally realized that this is a bug with the Django development server! I don't seem to have this problem when I include it in production and run it on my Apache server.
