This code:

Here's the file:
softfold.png http://forum.openscad.org/file/n20889/softfold.png
I would add some margins to that file, the object touches the image
edges. Depending on the algorithm, it could cause problems. I would also
reduce the image size by half or more, as the surface command really
eats memory.
If you want to create solids from such images, there are several ways to
do it, the surface command may not always be the best or easiest. See
attached file for the result of an alternative approach.
