Hi Lars, this is a bit late, but I got around this by catching "hide" on 
the combo's popup window:

   popwin = GTK_COMBO (fred)->popwin;
   gtk_signal_connect (GTK_OBJECT (popwin), "hide",
                       GTK_SIGNAL_FUNC (selected),
                       (gpointer) xx);

works in gtlk1.2 anyway
