This is with the gtkmm that you have built yourself, right, and from

Do you have a backtrace?

If you are the only one who can reproduce this then I'm afraid you will
need to do some investigtion yourself. If this was happening for other
people they would notice rather quickly.
At the very least, you might derive a Gtk::Window and put some std::cout
output in its destructor, to see when that is being called.
You could also try to handle the underlying GtkWidget's "destroy"
signal. If that is being emitted too soon, you could investigate why.
