 To reproduce on ogs21, say:

 - Checkout trunk/Image and trunk/Shared

 - Set PYTHONPATH to something like:

 /home/maky/lib:/home/maky/ubuntu/usr/lib/python2.5/site-packages:../Shared

 - from trunk/Image, execute:

 rm -r /data/tests/imageref_db /data/tests/thumbnail_db
 python process_pages.py --chert --cache-size=1 /media/newcastle/disk
 /indexed-pages10.tar.bz2 /data/tests/imageref_db /data/tests/thumbnail_db

 Output will be, e.g.
