also, I don't see how RefPtr is relevant to the given example struct; it's only for Glib::Object instances, i.e. things that themselves wrap GObjects, as RefPtr is implemented via GObject refcounts.
...in the currently stable glibmm, at least. Beyond that, in the next release, it'll be an std::shared_ptr, layering a different layer of refcounting over GObject's own.
but the point stands: what would a RefPtr to a char* or any other simple property type even mean? They should just be returned by value, not by reference.
