Does not serialize Models and QuerySets successfully in Django 1.2

[micolous]

I had issues with the library trying to serialise QuerySets and Models. In the case of Models, it tries to serialise one of the internal Django attributes, and fails.

I've written a patch around it -- it's not pretty but seems to do the job.
