I am just performing massive upgrade to etch. And I see plenty of
errors like quoted below.

IIRC there were some changes in X11 directories layout. Maybe
emacsen-common miss some dependency. But ... I believe it would
be easier and better to use /etc/locale.alias.

It seems that I incorrectly classified the problem, it seems to
be in emacs20, not emacsen-common. After I removed emacs20, the
problem disappeared.

I am tagging all these bugreports +pending +patch, since they will be dealt
with by the NMU I am preparing. I am currently waiting for news on the lenny
release before actually upload, but since is taking longer than expected I
will probably upload really soon.

Changes go much further than an usual NMU, but since I received no reply on
this during some long time I will proceed with it. Changes can be tracked at
the git repo

git://git.debian.org/git/users/agmartin/my-emacsen-common.git

(browseable through
