Okay, that's weird.  I've just written a test like so (against current CVS):

    def test_numpyConversion( self ):
        """Test that we can run a numpy conversion from double to float 
for glColorArray"""
        import numpy
        a = numpy.arange( 0,1.2, .1, 'd' ).reshape( (-1,3 ))
        glEnableClientState(GL_VERTEX_ARRAY)
        glColorPointerf( a )
        glColorPointerd( a )

and it produced no errors.  Can you produce a minimal test that shows 
the error occurring?  The system *should* be able to convert from double 
to float (as shown with this test).  Could be that it's some bug I don't 
recall fixing, but that doesn't seem likely.

Good luck,
Mike
