7574	EmailMultiAlternatives and send_email do not handle ugettext_lazy translated strings correctly	gary.hutspot@…	Matthias Kestenholz	"When trying to send email with a subject that is lazily translated, the following TypeError is thrown:

argument of type '__proxy__' is not iterable

Cut and paste compatible example:
{{{
from django.utils.translation import ugettext_lazy as _
from django.core.mail import send_mail
from django.conf import settings

# If you do not have smtp running on your local system, specify your smtp server here
settings.configure(EMAIL_HOST='your.smtp.server')

send_mail(_('Subject here'), 'Here is the message.', 'from@example.com', ['to@example.com'], fail_silently=False)
}}}

Produces:
