Quickhelp for Python in Emacs autocomplete.el?

I am using Emacs 23.1.1 on GNU/Linux with autocomplete.el 1.3 and Ropemacs 0.6.

In Lisp programming, autocomplete.el shows the documentation (known as 'QuickHelp' in autocomplete.el) of the suggested completions. Python completion with ropemacs works, but does not show quick help for the Python completion. Is it possible to enable it and did somebody make it work?
