I've got Segmentation Fault :_(
My function to change active widget looks like:

void
przejdz (char *element, GtkWidget * mw)
{
// Change active widget to widget with name element
  GtkWidget *w;
  if ((w = lookup_widget (mw, element)) == NULL)
    return;
  gtk_widget_grab_focus (w);
  return;
}

and for example:

przejdz("entry3",main_window);

make 1 or 2 seconds without reaction (coursor doesn't) change it's position
(program freezes) and after this time window closes with Segmentation Fault
message.
