I don't know if this can help you or not. I always follow the Poseray 
construction where uv_mapping is concerned:

#declare P_image = My_image_diffuse;
#declare F_ = finish {My_settings}
#declare N_image = normal {My_image_normal bump_size My_bumpsize 
My_modifiers}

#declare My_material =
material {
   texture {uv_mapping
     pigment {P_image My_modifiers}
     finish {F_}
     normal {N_image My_modifiers}
   }
}

Alternatively, the uv_mapping can be placed at the pigment and/or normal 
level. Simple construct, but then I am not familiar with your workflow 
in this. Still, I guess that you are right in assuming that it might be 
a tiny little thing.
