The Wakari team has been busy updating Wakari to IPython 1.1, and things have been moving fast on the Bokeh side as well. It looks like there was a little collateral damage to Wakari-Bokeh integration in the process. The Wakari team is looking into this right now and there should be a fix in place at the latest, early next week. I will post back here when things are back in order. Full Bokeh integration on Wakari (notebooks plots, persistent plot hosting, etc.) are all planned features. Thanks for trying things out and thanks for your patience!
