Django 1.5.1: Sending HTML mails with Unicode string contents fails

Hi all,

a while after upgrading from Django 1.4 to Django 1.5.1 (using Python 2.6.5), I realized
that I no longer got any of the automatic e-mails that are normally sent when an error
occurs.

Then problem occurs only when HTML emails are sent, sending plain-text emails works
without problems.

In settings.py, my LOGGING configuration is:

LOGGING = {
'version': 1,
'disable_existing_loggers': False,
'filters': {
'require_debug_false': {
'()': 'django.utils.log.RequireDebugFalse'
}
},
'handlers': {
'mail_admins': {
'level': 'ERROR',
'filters': ['require_debug_false'],
'class': 'django.utils.log.AdminEmailHandler',
# 'include_html': True, # Doesn't work with Django 1.5.1.
}
},
'loggers': {
'django.request': {
'handlers': ['mail_admins'],
'level': 'ERROR',
'propagate': True,
},
}
}


That is, emails are reliably received when include_html is set to False, but not when at
True, which used to work with Django 1.4.


At the management shell, with Django 1.5.1:

>>> from django.core.mail import mail_admins

# No Umlaut-characters --> ok.
>>> mail_admins(u"Test 1", u"Message Body", html_message=u"<h1>Ueberschrift</h1>")

# Umlaut-character in the subject --> ok.
>>> mail_admins(u"Täst 2", u"Message Body", html_message=u"<h1>Ueberschrift</h1>")

# Umlaut-character in the message body --> error.
>>> mail_admins(u"Test 3", u"Mässage Body", html_message=u"<h1>Ueberschrift</h1>")

# As before, Umlaut-character in the html message, but plain "" byte string, not u"" --> ok.
>>> mail_admins(u"Test 5", u"Message Body", html_message="<h1>Überschrift</h1>")


I'm not sure if the problem is with my code or in Django.
Can someone help please?

Best regards,
Carsten
