New PyPI Release

[nsomaru]

edit: The fix for this is to install directly from the git repository, PyPI release is not the latest code on master. Leaving the below for @tBaxter reference.

Good Day TBaxter,

Thank you for a the project. I had been using it fine with python2, but a migration to python3 is tripping me up and I'm not sure how to fix it. I hope you can help.

The exception:

This is how I'm creating the card (it works fine):

    def vcard(self):
        the_card = card_me.vCard()
        the_card.add("n")
        the_card.n.value = card_me.vcard.Name(given=self.user.name)
        the_card.add("fn")
        the_card.fn.value = u"%s" % (self.user.name)
        the_card.add("email")
        the_card.email.value = self.user.email
        the_card.email.type_param = "WORK"
        the_card.add("tel")
        the_card.tel.value = "%s" % self.mobile_number
        the_card.tel.type_param = "WORK"
        the_card.add("adr")
        the_card.adr.value = card_me.vcard.Address(country=(self.country.name,))
        the_card.adr.type_parm = "HOME"
        the_card.add("photo")
        buf = BytesIO()
        img = Image.open(self.image.file)
        img.thumbnail((600, 600), Image.ANTIALIAS)
        img.save(buf, img.format)
        the_card.photo.value = buf.getvalue()
        the_card.photo.encoding_param = "b"
        the_card.photo.type_param = img.format
        if self.company_name:
            the_card.add("org")
            # we need to do this like this because of the way this is serialised
            the_card.org.value = (self.company_name,)
        if self.website:
            the_card.add("url")
            the_card.url.value = self.website
        return the_card

However, when trying to serialize as so the problem occurs:

@login_required
def create_vcard(request, username):
    user = get_object_or_404(User, username=username, is_staff=False)
    response = HttpResponse(
        user.profile.vcard().serialize(), content_type="text/vcard" # problem occurs here
    )
    filename = "contact.vcf"
    response["Filename"] = filename
    response["Content-Disposition"] = "attachment; filename=%s" % filename
    return response

Thanks again for the project. Apologies if this is the wrong place to ask this.
