It seems that wl-window-deletable-p returns non-nil for non-deletable
window.  Try to write the below code in your draft buffer which raises
the error by wl-draft-kill, and evaluate it (C-x C-e at the right of
the last closing paren).  Please confrim the result which is showed in
minibuffer.  Recent emacs should return "(t nil nil)".

(list
 (fboundp 'window-deletable-p)
 (null (one-window-p))
 (wl-window-deletable-p))
