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 <at> gnu.org mailing list.

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

Start emacs -Q. On being user weg I use tramp to access on 
localhost  the file 
-rw-r--r--  1 laura laura        6 2009-07-05 09:31 test3.txt
in /tmp.


edit and save.  *Messages* has these lines:

Saving file /scp:laura <at> localhost:/tmp/test3.txt...
Wrote /scp:laura <at> localhost:/tmp/test3.txt
File error: Error while changing file's mode /scp:laura <at> localhost:/tmp/test3.txt

The file is updated under my ownership.

-rw-r--r--  1 weg   weg         27 2009-07-05 09:32 test3.txt

The backup file renamed properly: 
-rw-r--r--  1 laura laura        6 2009-07-05 09:31 test3.txt~

When  tramp access a remote system in an analogous situation there 
is no problem.  I have a copy of the  tramp debug buffer saved if needed.

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/23.0.95/etc/DEBUG for instructions.

Last days I have fixed some few bugs in `tramp-do-copy-or-rename-file-directly',
which does the work in your case. Could you, please, check with a fresh
built, whether the problem still happens?

Best regards, Michael.

I compiled the current version of 23.0.95.  

Tramps behaves the same way as originally
reported.  Then I tried editing another file in a
different directory with permission 664 owned by
the same user (not me).  But it does not open.
The following is a copy of *Messages* that
includes references to the two episodes:
  
  Tramp: Opening connection for laura <at> localhost using scp...
  Tramp: Waiting 60s for local shell to come up...
  Tramp: Sending command `ssh localhost -l laura  -q -e none && exit || exit'
  Tramp: Waiting for prompts from remote shell
  Tramp: Found remote shell prompt on `localhost'
  Saving file /scp:laura <at> localhost:/tmp/test4.txt...
  Wrote /scp:laura <at> localhost:/tmp/test4.txt
  File error: Error while changing file's mode /scp:laura <at> localhost:/tmp/test4.txt
  Quit [6 times]
  Mark set
  GNU Emacs 23.0.95.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.16.1) of 2009-07-07 on gauss
  Quit [6 times]
  File error: Copying directly failed, see buffer `*tramp/scp laura <at> localhost*' for details.
  find-file-noselect-1: Wrong type argument: arrayp, nil

The buffer *tramp/scp laura <at> localhost* is empty.

If you need the a copy the debug buffer (level 8) please let me know.

Thank you.
