Django ckeditor compatibility issue/error

I’m getting the following error if I enable the django ckeditor widget with my formfield override in the admin.py

However it should be noted that the regular override using the Textarea widget works fine.

formfield_overrides = {
    models.CharField: {'widget': TextInput(attrs={'size':'200'})},
    models.TextField: {'widget': Textarea(attrs={'rows':100, 'cols':100})},
}

THE ERROR DEBUG INFO:

Did you include (r'^ckeditor/', include('ckeditor.urls')), in urls.py?

I think it also requires no $ at the end.
