Yes, the entry was this:

(""
  "Directory list of /home/andy/.w3m/"
  nil
  (17867 20235 881557)
  nil
  nil)

As you said, removing that entry solved the problem.

Considering the case you explained above, it seems strange that the
Directory listing of /home/andy/.w3m/ triggered the generation of that
empty string.

I tried to open with emacs-w3m the url: file:///home/andy/.w3m/ without
the patch form Naohiro, and the resulting entry in ~/.w3m/.arrived is:

("file:///home/andy/.w3m"
  "Directory list of /home/andy/.w3m/"
  (18263 61513)
  (18263 61510 425407)
  nil
  nil)

which is correct.

I can't reproduce the situation in which opening that url will end up in
an entry with an empty string.  It is entirely possible that the problem
happened in one of my debugging/experimentation sessions.

I tried it by evaluating this sexp: `(w3m-goto-url "/")' and it worked;
no empty string in the `~/.w3m/.arrived' file.

Many thanks for your help.

With my best wishes,
Andrea.
