Commented Unassigned: no outgoing dirEdge found [24391]

Using Version 1.4 of DS.

At times when I do an intersection with this call:

IFeatureSet secondClip = ifsIncidentCatchments.Intersection(siteDesignArea, FieldJoinType.All, null);

I get this error:

no outgoing dirEdge found [DotSpatial.Topology.coordinate)

Attached are the two files that show the error.

catchment.shp=ifsIncidentCatchments
siteDesignArea.shp=SiteDesignArea

One way to get around this is to slightly buffer the calling FeatureSet (ifsIncidentCatchments) by some random tiny amount and re-doing the intersection.

Hello all..
Two years left, but this problem still remains.. Who knows how to fix this error, if geom.buffer(0) is not work?
My code, which raised this error:
IFeature feat1=somefeature.buffer(0);
IFeature feat2=anotherfeature.buffer(0);
feat1=feat1.union(feat2);
Thanks
