i already tried this. sadly, the properties values get lost because the
Glib::Properties already do register a "set_property" handler in the
corresponding GWidgetClass (when registering the GType) which points to
custom_set_property_callback() (in property.cc).

then later, when a new GObject (which was not yet wrapped) gets its
properties assigned, custom_set_property_callback() is called, which
sees there is no wrapper for the property yet and silently discards the
value. so there is no value to save when postcreate() is called.

the only solution i can see is to make glade call an additional callback
between GObject creation and property assignment (see my previous mail
to the list: we'll have to talk to the glade team about it).
