Pulp

If you have a mongoengine converted unit type, you cannot publish it using the platform's FileDistributor even if the plugin's subclass of FileDistributor has been correctly implemented. For example if platform is at HEAD of master, and you test against the in-development puppet conversion to mongoengine then you can run the following commands to cause this failure using a mixture of pulp-admin and httpie:

pulp-admin -u admin -p admin puppet repo create --repo-id=zoo-puppet --feed=http://forge.puppetlabs.com --queries torssh
pulp-admin puppet repo sync run --repo-id zoo-puppet
http --verify no --auth admin:admin POST https://localhost/pulp/api/v2/repositories/zoo-puppet/distributors/ distributor_type_id=puppet_file_distributor distributor_id=asdf
http --verify no --auth admin:admin POST https://localhost/pulp/api/v2/repositories/zoo-puppet/actions/publish/ id='asdf

You'll see the following traceback in the celery worker running the publish for distributor=asdf:

Exception from server requesting all content units for repository [zoo-puppet]
Traceback (most recent call last):
  File "/home/bmbouter/Documents/pulp/server/pulp/plugins/conduits/mixins.py", line 716, in do_get_repo_units

    type_def = type_defs[type_id]
KeyError: u'puppet_module'

It would be good if this was fixed in a way that generalized to more gracefully handle type_def lookup failures all over the codebase.
