Details:

In catalog mode, the Crop program accepts a catalog to make many crops in one
command. However, when the catalog doesn't have any usable rows, it crashes
(segmentation fault). 

Crop should print a warning and abort instead of an ugly segmentation fault. I
am now busy implementing the fix.

This bug was reported by Geoffry Krouchi.
