This is a harmless error. Check this:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513216

BTW, when you saved or restored the image, did you see any error
messages other than the above one ?
How about the image dir ? Could you please run:
find /home/partimag/$YOUR_IMAGE -print
(Replace $YOUR_IMAGE with your image name)
then post the results ?
