using Gtk::Switch causes segmentation faults on window close

When you use Gtk::Switch it causes segmentation fault on window close in some situation.

Example code:

example_seg.cpp - causes segmentation fault on window close.

example_ok.cpp - runs ok

Compling

g++ -g example_seg.cpp -o example_seg `pkg-config gtkmm-3.0 --cflags --libs`
g++ -g example_ok.cpp -o example_ok `pkg-config gtkmm-3.0 --cflags --libs`

When defining variables in order:

Gtk::Switch sw;
Gtk::Window w;

as in: example_ok.cpp there is no error.

When defining variables in order:

Gtk::Window  w;
Gtk::Switch sw;

as in: example_seg.cpp the applications crashes with segmentation fault when application window is closed.
