bug#1677: 23.0.60; GNUS groups and non ascii characters: mails disappear

[Sebastian Rose <sebastian_rose@gmx.de>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:




I use a group name containing the german letter `ö'. My whole Debian
System is utf-8 based and I save all files (.emacs, .gnus.el....) in
utf-8 by default.

Here is the relevant part of an example .gnus.el:

(setq nnmail-split-methods
      '(("list:monotone-devel" "Subject:.*\\[Monotone-devel\\]")
        ("list:emacs-devel" "To:.*emacs-devel@gnu.org")
        ("unmöglich" "\\(To\\|CC\\|Sender\\|From\\):.*@example.de")
        ("mail:eingang" "")
        ))

In the group buffer `unmöglich' is displayed as

 nnml:unm\366glich

When I fetch new mails, the line in the group buffer changes as expected
to 

  6: nnml:unm\336glich

Moving point to that line and pressing SPACE, that is
(gnus-group-read-group &optional all no-article group select-articles),
makes all the mails disapear again, and the line looks like I have no
mails in that group anymore:

  0: nnml:unm\336glich

The summarybuffer does not open up. If the summary buffer was opened
already, it's contents are not changed to reflect the contents of
`unmöglich'.

sh$ ls -l ~/emacs/gnus/Mail/
drwxr-xr-x 2 sebastian sebastian    4096 23. Dez 12:48 unmöglich
drwxr-xr-x 2 sebastian sebastian    4096 23. Dez 15:12 unm?glich

...revealsI have two directories for this group, both of which were
touched today:

`unmöglich' was touched when I started emacs/gnus.
            This is, where I found 3 out of 6 mails (maybe the `6: ...'
            was wrong in the group buffer?).
`unm?glich' was touched when I fetched Mail (or when I hit the spacebar
            in the group buffer - not shure yet).
            This one is empty.






If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.60/etc/DEBUG for instructions.
