RestKit: RestKit 0.20.0rc1 change causes Core Data code to fail

Hello,

We have some code that was working under pre6, but now generates Core Data errors with rc1. Any help would be appreciated. We see the error both when we run our code and when we run the unit tests.

The managedObjectStore is empty when the test case runs.

Here is the error message in the console:

Test Case '-[RecipientRemoteServiceImplTest testEntityMappingInManagedObjectStore]' started.
