Yes.

gtk_combo_box_new_text() creates a combobox, you dont want that -
you just want your combobox to contain text.

So, add "items" to your combobox via the glade tool, if the combobox
has "items" property set on it - then libglade will create it as
if it had been created with gtk_combo_box_new_text().

If the items are dynamicly created (usually the case), then you could:
    a.) do what gtk_combo_box_new_text() does to the combobox manually in
        your code (i.e. create the liststore with a G_TYPE_STRING column).
    b.) create it with an "items" property set - but just clear the combobox
        text after loading the glade file

Cheers,
