Hi,

sorry for the late answer.

Obviously, since you wouldn't report here ;-)

Wow the f*? ...

... sigh. I think I see what goes wrong here. How did it appear not in
earlier times (the problematic code is in there since 3.x!).

libreoffice-common has a trigger which is supposed to run
make_lo_sync_extensions to do what it says when a extension is
installed/removed by touching the dir:

$ cat libreoffice-common.postinst
#!/bin/sh

set -e

[...]
validate_extensions() {
  INSTDIR=`mktemp -d`
  if HOME=$INSTDIR /usr/lib/libreoffice/program/unopkg list --bundled >/dev/null 2>/dev/null; then
	HOME=$INSTDIR /usr/lib/libreoffice/program/unopkg validate -v --bundled
  fi
}

make_lo_sync_extensions() {
	touch /usr/lib/libreoffice/share/extensions
}

if [ "$1" = "triggered" ]; then
        for triggername in $2; do
                case "$triggername" in
                        # new "bundled" extensions (since 3.3)
                        "/usr/lib/libreoffice/share/extensions")
                          make_lo_sync_extensions
                        ;;
[...]
                esac
        done
fi

[...]
$

So I guess dpkg removes /usr/lib/libreoffice/share/extensions i(it is
still "owned" by libreoffice-common though. Should it happen?) and
nevertheless libreoffice-common is triggered the touch is fired and you
end up with that 0 byte file :/
