I'm not terribly keen on adding this sort of specific functionality to all
views, just so we can call a method in one class.

It seems like a better route would be for BubbleIconView to explicitly register
itself as a listener on the bubble delegate, to be called when the bubble
closed.

Or observe the bubble as a widget observer.

I will try to find a way around it.

Thanks, msw@, I will take a look at what's involved.
