As these are not supported by squeeze's dpkg, this can cause upgrade
problems (see below).

(OOC why the duplicates?)

This only guarantees that this dpkg version will be configured before
installing this package, but not that the currently running dpkg will
be that one version, so the upgrade from squeeze can still fail due to
parser errors for the unknown triggers directive.

This is of course fine, though.
