Null ref exception on simple test input

[GoogleCodeExporter]

Thats what I get for quick fixing.
Sorry for the inconvenience.

Do this change to method:
private static void FinalizationConvexHull( DTSweepContext tcx )

Change line:
        TurnAdvancingFrontConvex( tcx, n2, n3 );
To:
        TurnAdvancingFrontConvex( tcx, n1, n2 );

Change previous patch to:
        n1 = tcx.Front.Tail.Prev;
        if( n1.Triangle.Contains( n1.Next.Point ) && n1.Triangle.Contains( n1.Prev.Point ) )
        {
            t1 = n1.Triangle.neighborAcross( n1.Point );
            RotateTrianglePair( n1.Triangle, n1.Point, t1, t1.OppositePoint( n1.Triangle, n1.Point ) );
            tcx.MapTriangleToNodes( n1.Triangle );
            tcx.MapTriangleToNodes( t1 );
        }                
        n1 = tcx.Front.Head.Next;
        if( n1.Triangle.Contains( n1.Prev.Point ) && n1.Triangle.Contains( n1.Next.Point ) )
        {
            t1 = n1.Triangle.NeighborAcross( n1.Point );
            RotateTrianglePair( n1.Triangle, n1.Point, t1, t1.OppositePoint( n1.Triangle, n1.Point ) );
            tcx.MapTriangleToNodes( n1.Triangle );
            tcx.MapTriangleToNodes( t1 );
        }
