A custom provider that does not return language results in a NullReferenceException in ProjectPipeline. Even though ProjectPipeline is not the problem, it should not throw an NullReferenceException.
The problem is that a custom provider should never return a content instance where Language is null. This is not a supported scenario. If it is ILocalizable, it should have a language.
