it would be my guess that all of the widgets are getting the signal to be
destroyed and you're only preventing the dialog from being, not its contents.

ignoring the fact that it never exits the following code works:

use Gtk2 '-init';
my $dialog = Gtk2::Dialog->new (
                        "Test", undef, 'modal',
                        'gtk-cancel', 'cancel',
                        'gtk-ok', 'ok');
Glib::Timeout->add( 500, sub {
                $res = $dialog->run;
                $dialog->hide;
                print "$res\n";
                $res eq 'ok';
        });
Gtk2->main;

so long as you click ok the dialog will pop up every 1/2 second. if you click
cancle it won't any more. notice that run is blocking, hide causes the dialog
to disappear. i probably should have to be as complicated as what you were
describing.

if you're not using a Gtk::Dialog then i would suggest doing so as much of
what you're trying to deal with is handled for you with them.
