OK, I have debugged this somewhat further. I can still reproduce this
behavior in the following conditions:

- Latest CVS of Gnus in ~pavel/.Emacs/Work/gnus/lisp
- no init files (no .gnus etc.), only this in ~/.emacs:

(setq debug-on-error t)
(setq load-path (cons "~pavel/.Emacs/Work/gnus/lisp" load-path))
(setq gnus-select-method '(nnfolder ""))

- no directory Mail, no News etc. In fact, the user is my test user which
  is "empty" ;-)

- run emacs -f gnus
- You will see:

       9: nndoc+gnus-help:gnus-help
       *: nndraft:drafts

- Enter nndoc+gnus-help:gnus-help, and press RET on the first Article.
- Now press Mouse-2 on Lars' email (larsi@gnus.org (ding)) in From:

Debugger entered--Lisp error: (wrong-type-argument window-live-p #<window 7>)
  select-window(#<window 7>)
  widget-button-click((down-mouse-2 (#<window 7> 14 (95 . 7) 36044147)))
  call-interactively(widget-button-click)

Can you reproduce that too? It does not happen with Gnus from Emacs'
pretest.
