It's a message, not an error (unless you have debug-on-error non-nil).
It sounds like your smb share is returning weird file results.
See eg http://debbugs.gnu.org/10928

What do:

ls -l /smb/.dir-locals.el
ls -ld /smb/.dir-locals.el

return?

Adding an entry for /smb to locate-dominating-stop-dir-regexp ought to
avoid the issue:

net\\|afs  ->  net\\|afs\\|smb

XEmacs doesn't have directory local variables, does it?
For a slightly less antediluvian experience, you could revert to Emacs
22.3, which doesn't have them either. ;)
