I'm not sure about wordpress specifically... but there's an imagemagick example for using the "gravity" option to crop the image in different places.  A "north" value tends to work well for profile/avatar images because usually the head is near the top of the image.  http://www.imagemagick.org/Usage/thumbnails/

So I guess, you could automatically do it for the person, and then give them the option to change it and specify their own thumbnail if they don't like it.
