Status of toolbar/toolmanager changes (not working for me)?

I'm using v1.5.1 and I was reading the discussion on

and trying to reproduce the toolbar manipulation shown at

I can't get it to work from either regular python or ipython
(console), at least not with my WXagg, GTKagg or GTKCairo backends.

In my matplotlibrc I have set toolbar to be toolmanager.

After successfully getting a figure window with fig, ax =
plt.subplots(), I find that fig.canvas.manager.toolbar is None and
there is no toolmanager attribute in the manager.

Did I miss something that has changed, because the pull seemed to
apply to 1.5.1?
