There's something very strange going on here, the output ppm from 
crater_dat.pov causes a segmentation fault and dumps core with 
ImageMagic,  but ImageMaic has no problem opening other ppm files that
I create with POV 3.5 RC3, I'm not including any different command line
options or anything. 

I buess it's something to do with the hf_gray_16 in global settings. 

Yes commenting out hf_gray_16 before rendering allows ImageMagic to open
the file, but when rendering crater.pov POV now says: 

height_field {


  "crater_dat" <----ERROR


Parse Error: Unsupported number of colors (0) in PPM image.
