Blogmaker works with Django 0.96, it does not work with the trunk version of Django. Here is a partial list of incompatibilities between Blogmaker and Django trunk:

• clean_data has been renamed to cleaned_data
• Problem with non-ascii data in tools - see Issue 6
• Possible problem with expand_shortcuts() (forum post)

The above is just the things we know about; a full list of backwards-incompatible changes in Django trunk is here: http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges.
