Bug#573214: locales: sv_SE.ISO8859-1 locale suddenly invalid(?)

[Peter Krefting <peterk@debian.org>]

Package: locales
Version: 2.7-18lenny2
Severity: normal

This configuration has worked for me for a long time:

  $ echo $LC_ALL 
  sv_SE.ISO8859-1
  $ echo $LANG
  sv
  $ echo $LANGUAGE 
  sv_SE.ISO-8859-1:sv:nb_NO.ISO-8859-1:nb:da_DK.ISO-8859-1:da:nn_NO.ISO-8859-1:nn:en_GB.ISO-8859-1:en_US.ISO-8859-1:en

But suddenly (probably after a recent security update) it has started
producing error messages:

  locale: Cannot set LC_CTYPE to default locale: No such file or directory
  locale: Cannot set LC_MESSAGES to default locale: No such file or directory
  locale: Cannot set LC_COLLATE to default locale: No such file or directory

That doesn't seem right. I still get Swedish sort order, Swedish messages
from software and Swedish manual pages where available, so something strange
is going on.
