I think the errors attribute needs to be a list (hence the name), so
try:
form._errors['name'].append('User name already in use')
I think errors is not only a list, but an instance of
django.forms.utils.ErrorList (or any subclass of it), which controls
the way errors are displayed in the form, as noted here:
http://docs.djangoproject.com/en/dev/ref/forms/api/#customizing-the-error-list-format
Now that I had a look at the source, there is an ErrorDict too, not
sure what gets used when, but it should be irrelevant to your problem.
