Newsticker is jealous

[Paul R <paul.r.ml@gmail.com>]

Hello,

I've been using newsticker 1.99 in treeview mode since I use emacs23.
Today I noticed a bug. It may be related to the retrieval method that
I changed recently, now I use wget external tool.

To reproduce, set the retrieval method to gnus, run newsticker in
treeview, then pop up scratch buffer and hit C-x 1. Now you can't see
any pane of newsticker, and he feels bad about that. Whenever he will
retreive some feeds, it will raise the error below :

-----------------------------------------

Debugger entered--Lisp error: (wrong-type-argument window-live-p #<window 6>)

  (save-excursion (set-window-buffer (newsticker--treeview-list-window) (newsticker--treeview-list-buffer)) (set-buffer (newsticker--treeview-list-buffer)) (if clear-buffer (let ... ...)) (newsticker-treeview-list-mode) (newsticker--treeview-list-update-faces) (goto-char (point-min)))
