justjs Cannot call method 'unshift' of undefined

The page() function in app.js makes the data.slots.crumbs get lost (which is used in layout.ejs). The page() function should read as follows:

function page(req, res, template, data)
{
  _.defaults(data, { slots: {} });
  _.defaults(data.slots, {crumbs: [], user: req.user, session: req.session });
  res.send(view.page(template, data));
}

instead of

function page(req, res, template, data)
{
  _.defaults(data, { slots: {} });
  _.defaults(data.slots, {user: req.user, session: req.session });
  res.send(view.page(template, data));
}

Hmm, which installment (subdirectory of examples/) are you looking at here? Or are you talking about the production version?

Blog 5 (but I see the same code is still in blog 6).

For the record: I'm just following the blogposts, so perhaps I missed something else.

Here's the stacktrace for more information:
