Tramp messages doesn't help :
the "*debug  tramp/scp puitg@ssh-leibniz.imag.fr*"  buffer just writes
that test.html is successfully copied to  the remote site, but it says
nothing about test.c not being copied.

It's weird : why does it succeed on test.html (exported from test.org)
and not on test.c (via org-publish-attachment) ?

Actually, you're right   :  the error  occurs  in eshell-shuffle-files
before the publish stage, as suggested by the lisp backtrace.

I don't know what  to do :  I want to use org-publish  but I can't use
the /ssh:user@host  syntax  because it's  an ange-ftp syntax  and  I'm
running xemacs (ange-ftp  on xemacs is   EFS, but  EFS doesn't  support
ssh).
