yafray problem

Hi!
i am making a little render with yafray,i have placed a are light closely and is the result of rendering:eek::eek:http://www.bulma-animation.org/u/p/6/2oo1s9att3vvp0ss1c4l0dcp0j.jpg

If the Blender internal render does the same thing it must be the normals, crtl-n, but it don’t look like it, hmmmmmmmm

We need more info:
Screenshots to see where the light sources are
GI method used (Skydome, Full GI, Full GI + photons)
