Can be reproduced like this locally:

nosetests -svx heat_integrationtests/functional/test_update.py
...
Traceback (most recent call last):
  File "/opt/stack/heat/heat_integrationtests/functional/test_update.py", line 193, in test_stack_update_provider_group

  File "/opt/stack/python-heatclient/heatclient/common/http.py", line 215, in _http_request
    raise exc.from_response(resp)
HTTPNotFound: ERROR: Not found

Here's the engine log related to the failure:

So it seems to be a regression related to the recent changes in nested stack validation.
