Also Emacs 23.4 makes no difference.

Now I made a bisect which ends up in

    commit 56fe788c8f4ff44430a79052d4d758a0a233ac40

        org-list: Fix visibility preservation

        * lisp/org-list.el (org-list-struct): Fix white spaces.
        (org-list-swap-items, org-list-send-item): Fix visibility
        preservation.

Understanding the problem or for a workaround resolve the merge
conflict of the revert seems too hard for me.
