The SOUP_STATUS_OK is not introspectable (see introspectable="0"). Also is defined in
Soup.AddressClass (no very intuituve). Better if it would be Soup.Status.OK

In Soup-2.4.gir you can see a field _libsoup_reserved3 defined:

grep -C 30 SOUP_STATUS_OK /usr/share/gir-1.0/Soup-2.4.gir

      <field name="_libsoup_reserved3" introspectable="0">
        <callback name="_libsoup_reserved3">

So I can't use predefined constants and I have to 
guess the values (only viewing .gir), assuming that in a future will no change.
