I have ever heared that POV-Ray's sphere sweep has bug, don't know what it is.
And has it been resolved?

There is two/three kind of bug, presently, on sphere sweep in povray 3.7:

1. homogeneous scaling by negative factor also affect the radius of the
spheres (do not do that, or see flyspray entry for a correction)
2. solver might display artefact when the segment is perpendicular to
the ray
3. when using a non linear_spline, the computation of the bounding box
might be so wrong, better manually bound it if you can.

I an not to sure that I got all of the nuance, there. But I started a 
thread called: Unofficial Blender to PovRay exporter, in 
povray.tools.general.

It is easy to miss things using the web interface. A newsgroup reader 
would be a better option.

Le Forgeron, very much I ask to excuse that I and Stephen littered in this
subject.
I nevertheless will repeat the question: Your links are full Povray  with a
patch
(uv mapping in sphere_sweep)???
