Absolutely.  Although I thought that was done.  But in any case, while
duplicate checking worked for a while, this was broken again by some
patch quite a while back.  

http://www.svenutcke.de/sw/f-spot/cleanup/

gives a short account of what happened.  A solution is available as
part of my face detection suite at

http://www.svenutcke.de/sw/Face/

(which can be made to calculate a hash on the image content alone),
but unless you really are interested in face detection, this is rather
overkill for your problem, I would think...
