Templates broken with pa.jquery

[shadowmint]

Using pa.jquery on an otherwise working site results in:

/eggs/Chameleon-2.14-py2.7.egg/chameleon/py26.py", line 13, in lookup_attr
return get(key)
TypeError: list indices must be integers, not str

• Expression: "breadcrumb.render(request)"
• Filename: ... uery-0.9.5-py2.7.egg/fa/jquery/templates/admin/master.pt
• Location: (line 37: col 77)
• Source: ... :content="structure breadcrumb.render(request)" />
  ^^^^^^^^^^^^^^^^^^^^^^^^^^
• Arguments: fs: <FieldSet - at 0x109ac2e90>
  model_plural: Milestone
  actions: {...} (1)
  model_label: Milestone
  breadcrumb: <list - at 0x10aad34d0>
  repeat: {...} (0)

  context: <MilestoneCustomModel_admin_edit_GET 1 at 0x109abcb10>
  model_class: <I18NModel Milestone at 0x109ac25d0>
  main: <PyramidPageTemplateFile - at 0x10aad2490>
  model_name: Milestone
  view: <ModelView - at 0x109ac2c50>

By removing:

config.include('fa.jquery')

The site works fine using the default old skin.
