gluTesselation - Combine Problems

Hey,
I've had a problem with gluTesselations for a long time but only
recently did they problem become bad.  I was usually tessellating
international boundaries and occasionally they would show tiny little
holes in them.  Now I am rendering counties and they are everywhere.
I have a terrible combineCallback that basically gives back one of the
points it tried to combine.  I have tried EVERY sample of a
combineCallback that I could find on google.  Even the one from the
SuperBible creates a geometric train wreck on my screen.


void combineCallback(GLdouble coords[ 3 ],
			        GLdouble *vertex_data[ 4 ],
			        GLfloat weight[4],
                                GLdouble **dataOut )
{
	//	this gets rid of warnings
	coords[ 0 ] = coords[ 0 ];
	weight[ 0 ] = weight[ 0 ];
	GLdouble *vertex = Drawable::getNewTessVerts( 6 );

	for( int j = 0; j < 3; ++j )
	{
		vertex[ j ] = vertex_data[ 0 ][ j ];
	}
	for( int j = 3; j < 6; ++j )
	{
		vertex[ j ] = 0;
	}
	*dataOut = vertex;
}


The sad thing is I don't even see where the geometry self intersects.
Here are my verts:
x,y,z
-2.2321 0.781845 0
-2.22749 0.781842 0
-2.22431 0.781833 0
-2.22223 0.781838 0
-2.22223 0.772144 0
-2.22247 0.772144 0
-2.22484 0.772153 0
-2.22719 0.772159 0
-2.23056 0.772158 0
-2.23146 0.772167 0
-2.23384 0.77217 0
-2.23424 0.772172 0
-2.23424 0.772223 0
-2.23423 0.772973 0
-2.23423 0.774753 0
-2.23423 0.774871 0
-2.23423 0.77582 0
-2.23421 0.777779 0
-2.2342 0.781848 0

There are some points that are close together but no self intersection
that I can see.

Here is a pic of the output.  I know I am drawing the lines correctly
b/c the yellow lines are drawing the same points that the tess is
supposed to be drawing.  I'd really appreciate any help.  Thanks...
