these multi-surfaces are in the layer with multi-polygons. OGR calls these geometries multi-surfaces. Investigating a bit more, I found curve-polygons within these multi-surfaces. Curve-polygons are in turn not ordinary polygons, but defined by curves, and v.in.ogr (most GIS software in general) does not support curves.
