This is a dpkg bug exposed by kernels >= 2.6.12 and which was fixed in
dpkg 1.13.8[0]; however that doesn't help anyone trying to debootstrap
chroots of pre-etch versions of Debian.
A trivial work around is to have the available file contain just a
newline rather than be empty, e.g. as in the attached patch[1] (which
is for --variant=buildd, but the same patch should apply to the plain
'woody' script and other distro versions).
