This - as Andreas says - is purely by using unopkg in a "unclean" environment.

Yeah, libreoffice itself had that problem, too. (see #669271)

Well, the fix is to make HOME point to something bogus (or a tempdir) so that unopkg
doesn't have the chance to write to it. In LO we do:

sync_extensions() {
  INSTDIR=`mktemp -d`
  export PYTHONPATH="/@OODIR@/program"
  if [ -L /usr/lib/libreoffice/basis-link ]; then
        d=/var/lib/libreoffice/`readlink /usr/lib/libreoffice/basis-link`/
  else
        d=/usr/lib/libreoffice
  fi
  if HOME=$INSTDIR /usr/lib/libreoffice/program/unopkg list --bundled >/dev/null 2>/dev/null; then
    if [ -e /usr/lib/libreoffice/share/prereg/bundled ] && readlink /usr/lib/libreoffice/share/prereg/bundled 2>&1 >/dev/null && [ -L $d/ure-link ]; then
      HOME=$INSTDIR \
        /usr/lib/libreoffice/program/unopkg sync -v --bundled \
        "-env:BUNDLED_EXTENSIONS_USER=file:///usr/lib/libreoffice/share/prereg/bundled" \
        "-env:UserInstallation=file://$INSTDIR" \
        "-env:UNO_JAVA_JFW_INSTALL_DATA=file://$d/share/config/javasettingsunopkginstall.xml" \
        "-env:JFW_PLUGIN_DO_NOT_CHECK_ACCESSIBILITY=1"
    fi
  fi
  rm -rf $INSTDIR
}

Note setting INSTDIR and the HOME=$INSTDIR's....

If you wanted to keep your maintainer scripts you need to do it the same way as above.

BUT better (and this is what almost all extensions INCLUDING voikko do since loooong before you packaged this)
is to unpack the extension into /usr/lib/libreoffice/share/extensions and do nothing (libreoffice-common has triggers
which call the above). This new path and unpacked contents is a feature since OOo 3.3 iirc....
