Indeed – the patch I sent was targeted at better error messages, not
at avoiding the error.  (I first tried to automatically load ox-org in
the relevant case, but that runs into circular require problems).

I could do a smaller patch which just changes the error message text
within o-e-barf-if-invalid-backend.  Or drop it if you feel it’s not
worth it.

As Nicolas said, it would be good to know if upgrading org fixes the
issue that you see.
