Re: Info.el --signals error repeatedly when at top of the tree

[T. V. Raman]

The call to signal appears to be coming from function 
Info-extract-pointer
--and appears to happen when this function is called from 
functon Info-prev
on line 
(Info-goto-node (Info-extract-pointer "prev[ious]*"
"previous"))
--I am infering this because I saw the 
"prev[ious]*"
 in the call above in the Messages buffer.

The new customization option that optionally preserves the
header line at the top of the frame may also have something
to do with whether this bug shows up --
see option 

(defcustom Info-use-header-line t
  "*Non-nil means to put the beginning-of-node links in an emacs header-line.
A header-line does not scroll with the rest of the buffer."
  :type 'boolean
  :group 'info)

--I've at least confirmed that this occurs under X with
emacs21 and emacspeak --but without my personal .emacs file 
--so that's at least one piece simplified out.
An Emacspeak user in Australia first reported this problem
on the Emacspeak list.
