Great.
As you already have the old deb, can you please repete the test, but
using dpkg -i instead of apt-get (to re-upgrade I mean ... I don't think
apt-get can downgrade).
That is just to narrow the search of the package to reassign the 4 bugs
:-)
But seriously, it's quite clear that something in this man-db package
it's triggering this ugly behaviour.
So, what's changed between 2.3.13 and 2.3.14 ?

Another thing that is changed is inside the md5sum file:
< a79d0fb7542beef4281c7d754707bac0 usr/bin/wrapper
< bc5ae3db0572b49aa938538f37c4147b usr/bin/man
< bc5ae3db0572b49aa938538f37c4147b usr/bin/mandb

> f9b7b6014efe84c9cea791c6e2b2f568 usr/bin/mandb
In version 2.3.13 the md5sum of /usr/bin/man and /usr/bin/mandb is the
md5sum of the shell scripts files that are in the .deb and are removed
inside postinst, while in the 2.3.14 md5sum its listed the digest of the
files that are installed after the postinst (hardlinks to
/usr/bin/wrapper), and not the digests of the files shipped inside the
.deb.
Does anybody know if this could be the trigger for this ugly stuff?
