Package: dictionaries-common
Version: 1.28.12
Severity: wishlist
Tags: patch
User: reproducible-builds@lists.alioth.debian.org

Hello maintainers of dictionaries-common,

While working on the “reproducible builds” effort [1], I have noticed
that the content of the file '/var/cache/dictionaries-common/hunspell.db' is
changing randomly.

The order of the comma separated values for the key 'hunspell-locales' is
random [2]. This can be reproduced when e.g. the hunspell-nl package is
installed (manually invoking 'update-dictcommon-hunspell' will rebuild the
file).

The attached patch sorts the values and will guarantee the order.

With kind regards,
Roland Clobus
