I have updated Glib::Property in the master branch. I've also added a 
description how to combine Glib::Property with Gtk::Builder. Description 
is added both to Glib::Property and Gtk::Builder. And the example 
program at gtkmm-documentation/examples/book/builder/derived now 
contains a DerivedButton that contains two Glib::Property members.

This fix can be added to a stable glibmm 2.62, when such a version is 
created. There is no new ABI or API. If it's considered a bug fix, it 
would be possible to add it to the glibmm-2-60 branch. But is it really 
a bug fix or a new feature?
