Error using TRAMP to visit a directory

Error using TRAMP to visit a directory

[Alan Hadsell]

I receive an error when I try to visit a directory with TRAMP (2.1.5)
with GNU Emacs (22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on
RELEASE).  The target system is a CentOS GNU/Linux system.  I get the
following backtrace when I set debug-on-error:

It appears to be trying to format the user name ("al") with format
"-8d", which certainly isn't going to work.  Not sure why the data is
not in the expected format.

Thank you for your report.

Unfortunately, I cannot reproduce this problem on my XP machine (using
a different target system and directory name, of course).

Sounds like Tramp is using ls-lisp emulation instead of running `ls'
remotely, which I don't think what should happen.  Can you post here
the contents of your *Messages* buffer with messages from Tramp
describing its workings, so we could see what it did?

I think the data is in the expected format, but it is unexpectedly
processed by ls-lisp, which does not expect the user and group that
aren't numeric.

Thanks for your help, Eli.  This was a false alarm; I had a partial
copy of an old TRAMP in my load-path, and things were getting
confused.  It's working just fine now.
