Reading through your test code it appears that fixtures will not work
because the pre_save signal does not have the 'raw' argument.
I have applied the patch contained in
http://code.djangoproject.com/ticket/5422 to my django source and I have
changed my mptt source to work with the patch. I've attached a patch that
should be backwords compatible for anyone without their django source
patched. Then hopefully when the django ticket is committed djanog-mptt
will work with fixtures for everyone.
