I found two things you need to do to avoid breakages: 1. Strip trailing slash for any argument (especially the first argument, e.g. the path) 2. Strip full path for old_path, as readlink -f is a beast in case you have symlink->symlink->dir or something like that
E.g. do: symlink_to_dir /usr/share/doc/libavifile-0.7-bin libavifile-0.7-common 1:0.7.48~20090503.ds-16.1~ symlink_to_dir /usr/share/doc/libavifile-0.7c2 libavifile-0.7-common 1:0.7.48~20090503.ds-16.1~ symlink_to_dir /usr/share/doc/libavifile-0.7-dev libavifile-0.7-common 1:0.7.48~20090503.ds-16.1~ In case this doesn't help, you might need to set DPKG_DEBUG=1 before running upgrade, or even mangle dpkg-maintscript-helper to have #!/bin/sh -x stanza.
