Hangs mid-way through writing rotated and cropped images

[Ian Sullivan]

After loading rev 113 up with a full book's worth of image files and getting them all set for proper rotation and cropping, I selected PNG output and it started writing out the images. It got all the way to image 32 in the first set before halting with this error message:

Ran into same error message on second attempt to crop using trunk code. Different book used for second attempt.
