No, I'm arguing with footnote 53:

# apt-get install libgraphite2-2.0.0
# apt-get install libgraphite2-3
# apt-get remove libgraphite2-3

# dpkg -L libgraphite2-2.0.0
/.
/usr
/usr/lib
/usr/share
/usr/share/doc
/usr/share/doc/libgraphite2-2.0.0
/usr/share/doc/libgraphite2-2.0.0/copyright
/usr/share/doc/libgraphite2-2.0.0/changelog.Debian.gz
/usr/share/doc/libgraphite2-2.0.0/changelog.gz
/usr/share/lintian
/usr/share/lintian/overrides
/usr/share/lintian/overrides/libgraphite2-2.0.0

That package is now non-functional, so we *need* a Breaks or similar.
Or a transitional package.

That could be. Either debsums or dpkg or both. The file was still in
.md5sums, but no longer in .list

And that bug discovered the above problem :-)
