Well, one of the windows has to be the window you set the
icon for, right? GTK+ can't just mind-read what window
you wat to set the icon on ;-)

You need to pass in toplevel->window, and as Havoc said, to avoid
that being null, you need to:

 "gdk_window_set_icon(). Call it in a signal handler connected to the
 "realize" signal on a GtkWindow with gtk_signal_connect_after()."
