It could very well be e.g. the resulting inode numbers and such, thus my
hypothesis at the top of the quotes above. Python people can have a look
at the fails.img.gz image, where the issue is notably reproducible from
the chroot in /var/cache/pbuilder/sphinxbase-build , building for
instance in /tmp/sphinxbase.
