I guess what is interesting is the self-intersecting and loop
self-intersecting polygons were built by ogr2ogr when converting from

Now that *is* interesting. Seems like maybe a bug in the ogr2ogr code?
Is it worth asking FW about this?
Martin,
In at least some polygon-assembly-from-arcs situations OGR just arbitrarily
connects arcs to arcs with matching end points with no regard to ambiguous
situations like bowties.
Best regards,
