The following scene is an example of the problem:

camera {location <-3,3,-3> look_at 0} // yadda yadda
default {texture{pigment {rgb 1}}} // yadda yadda
light_source {<1,1,-1>*9999 rgb 1} // yadda yadda

plane { // floor
 y,-1
}

difference {
 union {
  sphere_sweep { // problematic piece
   cubic_spline
   6,
   <1,.4,-3>,.4,
   <0,.4,-2>,.4,
   <.3,.33,0>,.33,
   <.2,.3,1>,.3,
   <0,.29,2>,.29,
   <-.5,.34,3>,.34
  }
  // insert anything here
  // sphere{0,1} // will do
 }
 // insert anything here, the cutaway area *will* have a shadow
 no_image
}

The sphere_sweep, when the no_image tag is in the difference{}, does not
have a shadow. Compare to when the no_image tag is not present. Spline type
doesn't seem to matter.

Any confirmation?
