    value: Crash harder if we don't have introspection info for an enum
    
    Currently, we accidentally crash if we don't have introspection info
    for an enum, because we try to unref the NULL info. Instead of fixing
    this so that it doesn't unref, let's ensure that we do have
    introspection info for an enum.
