Heh,
     Its not directly on-topic but I did bring it up; the
answer would obviously be:

     a.) Fail gracefully
     b.) Fall back to "my_object"less mode (heh)

In fact; I do write alot of code that looks like:
========================================================
if ((w = glade_xml_get_widget (xml, "foo")) != NULL) {
     my_app->foo = w;
     g_signal_connect (G_OBJECT (w), "clicked",
                       G_CALLBACK (foo_clicked), my_app);
}
========================================================

And then later go on to do:
========================================================
/* Show or hide this button if its available in this
  * particular skin.
  */
if (my_app->foo != NULL)
     gtk_widget_show (my_app->foo);
========================================================

The idea is to support a wide variety of features in the
code-base and also support a wide variety of products
that dont all include all the "dashboard extra features".

Ofcourse the point was to demonstrate that being responsable
for allocated resources is not that bad; actually its
the programmers responsability (a responsability that gets
harder to fullfill when there are dual and tripple standards...).

Cheers,
                        -Tristan
