   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.
