[Mapserver-dev] Fwd: Problem with WFS server and some donut polygons

I've discovered a problem with serving up certain donut polygons
through a
WFS getFeature request.  For most donut polygons, the data is served
up
correctly.  The polygon is described as a <gml:Polygon> with
associated
<gml:outerBoundaryIs> and <gml:innerBoundaryIs> elements.  However, if
the
centroid of the donut polygon falls within the hole of the donut, the
polygon is described as an empty <gml:MultiPolygon>.

The particular problem that I'm having is with Bedford County, VA in
the
2000 County Boundaries file downloaded from the National Atlas.  FYI,
I'm
using the DM Solutions Windows binary of Mapserver, version 4.0.2. 
The
data are Shapefiles.
