I just tested a little bit. If the class is derived from GLib::Object it
work fine. I also looked into the source code: Glib::Value<void*> is
much simpler and straightforward; Glib::Value<T*> depend on
ValueBase_Object (is this the reason why T must be derived from
GLib::Object?).

So I wrote my own template specialization like for Glib::Value<void*> and
this work fine too. It's just the question if it's really wanted that for
Glib::Value<T*> T must derive from GLib::Object (for me it's not logical).
