possible now to fix this bug in `dired-pop-to-buffer' where window space
for the *Marked Files* buffer is stolen from the wrong window in the
following configuration:

After fixing it this bug could be closed, and other possibilities
(e.g. to display this buffer above the minibuffer etc.) could be postponed
to 24.2 and discussed in a new feature request.
