  Why is there an ugly artifact running across my texture?

Can anyone point me to what is wrong?

I've circled the artifact in question in the attached image.

I'm using Moray 3.3 and POV-Ray 3.1 (it looks the same with POV-Ray 3.5),
(THIS IS NOT A MORAY QUESTION)

The object is a rotational sweep.

The texture is as follows:

#declare Dragon_Skin =
   material  // Dragon_Skin
   {
      texture
      {
         pigment
         {
            bozo
            color_map
            {
               [ 0.0     rgbft <0.109383, 0.890617, 0.109383, 0.0, 0.0> ]
               [ 0.5     rgbft <0.053166, 0.675967, 0.053166, 0.0, 0.0> ]
               [ 0.5     rgbft <0.0, 0.666667, 0.0, 0.0, 0.0> ]
               [ 1.0     rgbft <0.0, 0.479133, 0.0, 0.0, 0.0> ]
            }
            turbulence 0.9
            ramp_wave
         }
         normal
         {
            bumps , 0.05
            scale  0.00005
         }
         finish
         {
            ambient 0.4
            phong_size 0.0
            roughness 0.0
            reflection 0.1
            crand 0.15
         }
      }
   }

Thanks in advance.
