Protected enum in namespace can cause compilation issue

Having a protected enum inside a class within a namespace causes compilation issues when using the avoid-protected-hack option to shiboken. For example, the following code causes compilation issues:

namespace SampleNamespace {
    class SomeClass {
    protected:
        enum ProtectedEnum {
            ProtectedItem0,
            ProtectedItem1
        };
    };
}

The resulting auto-generated looks something like:

enum sample_SampleNamespace::SomeClass_ProtectedEnum_Surrogate {};

Obviously, the sample_SampleNamespace namespace does not exist and thereby causes compilation errors.
