Comment 2 for bug 426141

So, there are few issues here, but I've successfully reproduced what Jono saw. The error message that Firebug spits out is:

Y.Anim: invalid node: null

I assume that this is caused by the recent changes in the branch index page's markup. I'm looking into this now.

The other issue is that we don't really have a good error handling story just yet, but I'm working on that.
