This is off-topic for your question, but I notice that you have 
"ambient_light" without any color value in your global_settings.  Were 
you perhaps trying to adjust the overall brightness of your scene?  If 
that's the case, you might need to use "assumed_gamma" instead.  (On my 
PC, for example, scenes tend to come out much too dark unless I use 
"assumed_gamma 1.0" or thereabouts.)

Hope this is of some use!
