item_form doesn't 'arrive at' your template with a filled in errors
dictionary. Rather, rendering of item_form checks for (accesses) the errors
attribute, which triggers validation and populates the errors dictionary.
If you ever (including during rendering in the template) attempt to access
errors, errors gets populated. So you need to change your logic so that you
do not generate a form that will get validation errors in cases where you
don't care to see those errors because of some other circumstance. Sorry,
it isn't quite clear to me what you are trying to do exactly so it's hard
for me to be more specific as to recommendations.
