class variables signature in doc

Hi

All around the documentation, there are plenty of places where the
signature of class variables is displayed straight and without any
formating.
For example
http://matplotlib.org/api/backend_bases_api.html?highlight=toolitems#matplotlib.backend_bases.NavigationToolbar2.toolitems

Is it possible to override this signature?
If I'm not wrong the autodoc_docstring_signature (sphinx
configuration) only works on callables

Thanks
Federico
