Ahh, I remember now there was something about not putting uv_mapping 
into the pigment statement (for unknown reasons, maybe a bug), that's 
why I do always use it this way:


#local T_Leaf = texture {
    uv_mapping
    pigment {image_map {png "AutumnLeaf1" interpolate 2} }
    finish {ambient 0  diffuse 1}
}


Sorry it did by mistake remove the uv_mapping keyword when I did remove 
the normal statement to simplify things.
