[Problems with [:lower:] and [:upper:] in UTF-8 locale]

I have now installed the latest versions of theses programs:

ii  bash           2.05b-3        The GNU Bourne Again SHell
ii  coreutils      4.5.7-1        The GNU core utilities
ii  grep           2.5.1-2        GNU grep, egrep and fgrep
ii  locales        2.3.1-14       GNU C Library: National Language (locale) da
ii  libc6          2.3.1-14       GNU C Library: Shared libraries and Timezone

The following statements work as expected:

$ grep [[:lower:]]                   
$ grep [[:upper:]]                   
$ case ... in [[:lower:]]) ... esac  # bash
$ case ... in [[:upper:]]) ... esac  # bash

The following don't work with non-ASCII characters when LC_CTYPE is
set to de_DE.UTF8

$ tr [:lower:] [:upper:]

Using "tr [:alpha:] '-'" I found out that non-ASCII letters (valid
letters in the de_DE locale) are not even recognized.  In the
de_DE.ISO-8859-1 locale both statements work correctly.

I don't know if this is related to this single program or can be
caused by problems in libc6 oder locales data.  Please tell me if you
think that I should report to coreutils instead.

So half the bug report is resolved,

        Torsten
