Newsticker is jealous

[Paul R]

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 :
