 union_() sometimes return an empty result. It seems like there is a bug
 with union_() if some vertices are too close to each other. I inspected
 the polygons and they seem to be valid (no self intersections). I created
 a SHP file and WTK file with a few problematic polygons. The polygons are
 in pairs, and if you call union_() on each pair, the result will be empty.
