Managed Object doesn't have stored record information

[jfhamel]

Hi, execution stops at this line:

		// That is possible if method is called before all managed object were filled with recordData
		// That may cause possible reference corruption (Core Data -> iCloud), but it is not critical
		assertionFailure("Managed Object doesn't have stored record information, should be reported as a framework bug")

in file CoreDataRelationship.swift.

It started occurring when I started using a NSManagedObject that inherits from another parent NSManagedObject. Never occurred before.

Thanks.
