Please write in simple English, because the emacs-w3m developers
aren't good at English reading. ;-)

Please describe as succinctly as possible:

Dear Bug Team!

I just updated emacs-w3m to the latest version on melpa.
When I tried to load any web site, the w3m popup an error said:

Debugger entered--Lisp error: (void-function --post-body--83063)
--post-body--83063((404 "text/html" "utf-8" 2477 "gzip" nil "http://weather.yahoo.co.jp/weather/jp/26/6100.html";))
  w3m-process-sentinel(#<process /usr/bin/w3m> "finished\n")

Whatever website I tried to load, the result is always the same except
the URL part of the message.

Could you please help to analyze what happened?

Thanks a lot!
