Comment 4 for bug 1664606

@Mike - as far as I can tell, it is behaving as expected. I am attaching the dxf file. In QCad each rectangle shows up as five points, of which the last point is a duplicate of the first point. And the closed flag is set so that it can be edited without breaking up the links.
