A copy of the original function gtk_dialog_new_empty shows us that it calls
internally function
gtk_window_set_transient_for (GTK_WINDOW (dialog), parent);
where parent is of the type GtkWindow or you could call :
GtkWidget* gtk_dialog_new_with_buttons (const gchar *title, GtkWindow
*parent, GtkDialogFlags flags, const gchar *first_button_text, ...)
You've probably called gtk_dialog_new which doesn't take a parent argument :(
here is the copy of the gtk_dialog_new_empty from the gtk source:
static GtkWidget* gtk_dialog_new_empty (const gchar *title, GtkWindow *parent,
GtkDialogFlags flags) {
GtkDialog *dialog;
dialog = g_object_new (GTK_TYPE_DIALOG, NULL);
if (title)
gtk_window_set_title (GTK_WINDOW (dialog), title);
if (parent)
gtk_window_set_transient_for (GTK_WINDOW (dialog), parent);
if (flags & GTK_DIALOG_MODAL)
gtk_window_set_modal (GTK_WINDOW (dialog), TRUE);
if (flags & GTK_DIALOG_DESTROY_WITH_PARENT)
gtk_window_set_destroy_with_parent (GTK_WINDOW (dialog), TRUE);
if (flags & GTK_DIALOG_NO_SEPARATOR)
gtk_dialog_set_has_separator (dialog, FALSE);
return GTK_WIDGET (dialog);
}

Subject: GTK:ERROR
Hello guys,
I'm writing here because I don't know where tell
this issue. I'm writing an app using pygtk and after calling the run
method of a gtk.Dialog, I get the following error:
Gtk:ERROR:/build/buildd/gtk+2.
0-2.16.1/gtk/gtkcontainer.c:2717:IA__gtk_container_propagate_expose: assertion
failed: (child->parent == GTK_WIDGET (container))
Cancelado
I
don't remember if I updated my gtk version, but I suppose I did and
it's the reason because I'm getting the error listed above, maybe a
bug? I've read the same issue happen Google Chromium.
Greetings.
