I have finally figured out what was going on. The dialogs were developed using Glade-2 and the buttons had "Reponse ID" set to 0 by default which is why they were returning when pressed.

So it is something like this: ======================================================================= #include <gtk/gtk.h> static void next_dialog(GtkWidget *button, gpointer user_data) { GtkWindow *parent = NULL; GtkWidget *dialog, *label; gint response, level; gchar *s; if (button) parent = GTK_WINDOW(gtk_widget_get_toplevel(button)); level = GPOINTER_TO_INT(user_data); level++; s = g_strdup_printf("Dialog %d", level); dialog = gtk_dialog_new_with_buttons(s, parent, GTK_DIALOG_MODAL, GTK_STOCK_OK, GTK_RESPONSE_OK, NULL); gtk_dialog_set_has_separator(GTK_DIALOG(dialog), FALSE); gtk_dialog_set_default_response(GTK_DIALOG(dialog), GTK_RESPONSE_OK); g_free(s); s = g_strdup_printf("This is dialog level %d", level); label = gtk_label_new(s); gtk_misc_set_padding(GTK_MISC(label), 12, 12); g_free(s); gtk_container_add(GTK_CONTAINER(GTK_DIALOG(dialog)->vbox), label); button = gtk_button_new_with_mnemonic("_Destroy Me"); gtk_container_add(GTK_CONTAINER(GTK_DIALOG(dialog)->vbox), button); g_signal_connect_swapped(button, "clicked", G_CALLBACK(gtk_widget_destroy), dialog); button = gtk_button_new_with_mnemonic("_Go Deeper"); gtk_container_add(GTK_CONTAINER(GTK_DIALOG(dialog)->vbox), button); g_signal_connect(button, "clicked", G_CALLBACK(next_dialog), GINT_TO_POINTER(level)); gtk_widget_show_all(dialog); gtk_window_present(GTK_WINDOW(dialog)); response = gtk_dialog_run(GTK_DIALOG(dialog)); g_printerr("level: %d, response: %d\n", level, response); if (response != GTK_RESPONSE_NONE) gtk_widget_destroy(dialog); } int main(int argc, char *argv[]) { gtk_init(&argc, &argv); next_dialog(NULL, NULL); return 0; } ======================================================================= Except that this program of course works. The variable that holds the response id is initialized to GTK_RESPONSE_NONE == -1, so whatever happens, you should not get 0 from gtk_dialog_run() unless - something sets it to 0 (note GtkDialog does not prevent you from using zero response id) - memory is corrupted In either case I would assume it is not GtkDialog what somehow breaks out of the inner main loop by force and/or sets the response id to 0. You cannot expect much from reporting it to bugzilla either if you don't show how to reproduce the problem with GtkDialog.
