Emacs shutdown error

[A . L . Meyers]

Hello!

Have been frequently getting the following error message when trying to
exit emacs with C-x C-c or by using the menu File-Exit emacs:

Wrong type argument: listp, -b

The backtrace of this error is:

Debugger entered--Lisp error: (wrong-type-argument listp -b)
  w3m-arrived-shutdown()
  run-hooks(kill-emacs-hook)
  kill-emacs()
  save-buffers-kill-emacs(nil)
  call-interactively(save-buffers-kill-emacs)

w3m is installed but was not active when attempting to shut down.

Suggestions most welcome as currently I must kill the emacs process to
exit emacs.

Lucien
