The attempt to parse out the olcDbDirectory in /var/lib/dpkg/info/slapd.postinst:get_directory() fails if there is more than one matching file, which there is on my system - there's an emacs backup file (i.e. olcDatabase={1}hdb.ldif~). Made the following patch:

                # Extract the directory for the given suffix ($1)
                for f in `get_all_slapd_conf_files`; do

which is more robust in the face of multiple matches. Extra credit is
given for explicitly grepping out junk.
