Sorry... here's a minimal scene.  As you can see, it only occurs with uv mapped
textures.

#declare R = 0.81; // 0.80 succeeds
#declare UV = true; // false succeeds
#declare MTL = 51; // 50 succeeds
global_settings { max_trace_level MTL }

#declare T =
texture
{
 #if (UV) uv_mapping #end
 checker
 texture { pigment { rgb x } finish { reflection R } }
 texture { pigment { rgb y } }
}

sphere { 0, 20 texture { T } hollow }

camera { location -z * 15 look_at 0 }
light_source { <10,0,-10> rgb 1 }
