Possible bug of BRepBuilderAPI_NurbsConvert

Load attached step file. And try to convert it to BSpline surface using API BRepBuilderAPI_NurbsConvert. The conversion is successful, but the tessellation failed. And the new shape shows topology error of unorientation. My OCC is 6.5.1.
Any suggestion is welcome. Thanks in advance.

Hi PG,

The cylinder is created in my software using OCC6.5.1. I have designed a B-Spline surface morph and editing module. So I want to convert the cylinder to b-spline surface to do editing opeartion.
Thanks.
