'pnmcrop' might also work for that.
Have you also tried 'mogrify' instead of 'convert' for cropping? Maybe 
it has more sophisticated cropping features, I don't know.

Would it be useful to pad all images to a common size before all further 
processing (add a white border around the smaller ones)? Just an idea...
Can you also prepare an example for this?
