[SOLVED] gtk_menu_popup() only works the first time?

[Miven]

I have this experimental little app that is supposed to pop up a menu on SIGUSR1:

GtkWidget *create_menu(void) {
    GtkWidget *menu1, *menuitem1;
    menu1 = gtk_menu_new ();

    menuitem1 = gtk_image_menu_item_new_with_mnemonic ("Menu Item _1");
    gtk_menu_shell_append (GTK_MENU_SHELL (menu1), menuitem1);
    menuitem1 = gtk_image_menu_item_new_with_mnemonic ("Menu Item _2");
    gtk_menu_shell_append (GTK_MENU_SHELL (menu1), menuitem1);

    gtk_widget_show_all (menu1);
    gtk_menu_popup (GTK_MENU (menu1), NULL, NULL, NULL, NULL, 0,
        gtk_get_current_event_time ());

    return menu1;
}

It works properly when first called. The silly little menu pops up under the mouse. Click an entry or hit ESCAPE and it goes away. Perfect.

I send a SIGUSR1 to the app, it catches it, prints a little confirmation that it did indeed catch it, then calls gtk_widget_show_all(menu1) and gtk_menu_popup(menu1, ...), and nothing. The menu doesn't reappear. First I thought the widgets were being destroyed, but then I'd surely get a segfault on the gtk_widget_show_all().

Any notion why this would be?

I figured it out. To sum up:

gtk_menus and all their automagic get confused by spurious events.

The gory details are here:
