Subject: bug#4142: [PATCH] 23.1 info.el::Info-goto-node - Wrong type argument: stringp, nil
Date: Fri, 14 Aug 2009 20:35:39 +0300 [thread overview]
Message-ID: <y6pmjo2c.fsf@jondo.cante.net> (raw)
Cf. Debian bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=531094
apt-get install w3m-el emacs23 emacs23-el
$ emacs -Q
M-: (setq debug-on-error t) <return>
C-h i m Emacs - w3m <return> i <return> 3
Debugger entered--Lisp error: (wrong-type-argument stringp nil)

nil)
Info-goto-node(nil)
Info-nth-menu-item()
call-interactively(Info-nth-menu-item nil nil)
Original bug submitter said:
I'm there on
(info "(emacs-w3m)Index")
and I can't enter
"3" which runs the command Info-nth-menu-item
The problem seems to be in lisp/info.el
(defun Info-nth-menu-item ()
"Go to the node of the Nth menu item.
N is the digit argument used to invoke this command."
(interactive)
(Info-goto-node
(Info-extract-menu-counting
(- (aref (this-command-keys) (1- (length (this-command-keys))))
?0))))
The value of Info-extract-menu-counting isn't checked for nil before
passing it to Info-goto-node.
