I agree this is a 2.2 blocker. It should be a very quick fix at least.

This area of distributor IDs and type IDs is very tricky. We may want to consider renaming one or the other at some point in the future to reduce confusion and ambiguity.

https://github.com/pulp/pulp/pull/552

build: 2.2.0-0.24.beta

To verify:

1. Create a repository using the following script instead of pulp-admin.
   This script adds a distributor with an ID that is different than it's type.

2. Enable the repository.

3. Bind the child to the repository.

4. Sync the child node.
