BadHeaderError: Header values can't contain newlines (got u'[Django] ERROR: discount_cards.views.register -> new_user.save -> value too long for type character varying(30)\n' for header 'Subject')

im currently testing dirty patch via adding at start of def queue_email_message

# file: __init__.py

email_message.subject = email_message.subject.replace(u'\n', u' ')

This sounds like an old Django issue. At least in 1.4, the AdminEmailHandler ensures the subject is devoid of new lines and isn't longer than 989 chars.

yes, Django 1.3
