Sorry, here's an even simpler working example that reproduces my problem, this
time even using just povray's default config:
#include "rad_def.inc"
global_settings {
   radiosity {
      Rad_Settings(Radiosity_OutdoorHQ,off,off)
   }
}

#include "colors.inc"    // The include files contain

camera {
location < -100,240,-20>
look_at  <0.0,20,0>


}
 sphere{<100,100,0> 20 finish{emission 1} pigment{White} hollow}

plane {
        <0, 1, 0>, -3

        pigment{color <1,1,1>}
        finish { reflection {0.5} ambient 0.0 diffuse 1 specular 0 }
        no_reflection


}
