This causes the geometry to be invalid from a simple features point of view (observable presumably with an isvalid test in postgis?). Presumably the concatenation code should be deduplicating things between chunks of the geometry. " defect closed normal OGR_SF 1.8.0 normal fixed gml nas astrid_emde
