Argh.

So the result of the subset query

SELECT OBJECTID as orig_ogc_fid, * FROM "lines" WHERE "text" = 'shape 2'

now is

305: OGR(1): OGR[3] error 1: Unrecognized field name OBJECTID.
305: OGR(1): Data source is invalid (Unrecognized field name OBJECTID.)

but OBJECTID is what was returned by

OGR_L_GetFIDColumn( layer )

Even, any ideas?
