Your .png is quiet big.
A resolution of 587 * 623 is a lot.
Try to figure out how many triangles this surface would have: 731 402.
This will bring Openscad to its knees.
I havent checked the manual, but I seem to remember that there is a limit
of 100*100 for the surface command.
Hope it helps.
P.S.: the 2 screen shots dont display
