The problem is already in `ibuffer' itself:

  (setq ibuffer-prev-window-config (current-window-configuration))
  (let ((buf (get-buffer-create (or name "*Ibuffer*"))))
    (if other-window-p
        (funcall (if noselect (lambda (buf) (display-buffer buf t)) 
#'pop-to-buffer) buf)
      (funcall (if noselect #'display-buffer #'switch-to-buffer) buf))

Saving the window configuration doesn't make sense if one of the
funcalls makes a new frame.

I hope it does.  But this is something users of ibuffer should try
first.

KILL should be optional here.
