Can you show the C and Lisp backtraces for that error?  You can run
Emacs under GDB with a breakpoint on this line of fileio.c:

  static Lisp_Object
  file_metadata_errno (char const *action, Lisp_Object file, int err)
  {
    if (err == ENOENT || err == ENOTDIR || err == 0)
      return Qnil;
    report_file_errno (action, file, err);  <<<<<<<<<<<<<<<<<<<<<<<<<<
  }

Thanks.
