 Hi :)
 I have now found out that my problem occurs after i call a function i wrot=
e,=20
I am a novice in this so i might have done something stupid then i wrote it=
=2E=20
It works as it intended but after calling it crashes the app at the next=20
lookup_widget i use. Segment fault (11) is the result of the crash. here is=
=20
the function:

   comboboxentry1 =3D gtk_combo_box_entry_new_text ();
  gtk_widget_show (comboboxentry1);
  gtk_table_attach (GTK_TABLE (table3), comboboxentry1, 1, 3, 12, 13,
                    (GtkAttachOptions) (GTK_FILL),
                    (GtkAttachOptions) (GTK_FILL), 0, 0);
  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1), _("PN1000#BAS"=
));
  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1),=20
_("PN1800#BAS/UTLAND"));
  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1), _("PK1000#UPP=

  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1), _("PK1800#UPP=

  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1),=20

  gtk_combo_box_append_text (GTK_COMBO_BOX (comboboxentry1), _("PN1770#KOMP=

}

Anyone see an error ??
