I get exactly the same thing.
Here's what I'm entering.
>>> import simplejson
>>> simplejson
<module 'simplejson' from 'C:\Python25\lib\site-packages
\simplejson-2.0.3-py2.5.
egg\simplejson\__init__.pyc'>
>>> from myproject.app.models import MyForm
>>> f = MyForm({'link': 'footext'})
>>> f.errors
{'text': [u'This field is required.'], 'link': [u'Enter a valid
URL.']}
>>> simplejson.dumps(f.errors)
Traceback (most recent call last):

raise TypeError("%r is not JSON serializable" % (o,))
TypeError: <django.utils.functional.__proxy__ object at 0x01182870> is

My test form is just:
class PrecedenceForm(forms.Form):
text = forms.CharField()
link = forms.URLField()
Thanks for looking. Any one have any other ideas?
