TemplateSyntaxError - Caught an exception while rendering: coercing to Unicode: need string or buffer, NoneType found

Hi all,

(Python 2.6, Django 1.2 beta 1)

I've got an error while editing object in admin panel in language tabs with all empty fields..

TemplateSyntaxError at /panel/pages/page/1/
Caught an exception while rendering: coercing to Unicode: need string or buffer, NoneType found

{% if add %}{% trans "Add" %} {{ opts.verbose_name }}{% else %}{{ original|truncatewords:"18" }}{% endif %}

All traceback: http://dpaste.com/184318/

ps. Thanks for project, it's great! ... I'm waiting for fixes for this issue..

regards.

Make sure you NEVER use a multilingual field as the only option in unicode of a model. ALWAYS check that this field is actually filled!

A possible way to do it is:

def **unicode**(self):
    if self.multilingual_field:
        return self.multilingual_field
    return self.pk
