[6.1] NameError: name 'active_id' is not defined

[Maxime Chambreuil (http://www.savoirfairelinux.com)]

On OpenERP 6.1, install a new DB with event module.

In Marketing menu,when I click on Reporting > Event Dashboard, I get :

Client Traceback (most recent call last):
  File "/home/max/openerp/web/6.1/addons/web/common/http.py", line 180, in dispatch
    response["result"] = method(controller, self, **self.params)
  File "/home/max/openerp/web/6.1/addons/web/controllers/main.py", line 1553, in load
    value = clean_action(req, action[0], do_not_eval)
  File "/home/max/openerp/web/6.1/addons/web/controllers/main.py", line 692, in clean_action
    action['context'] = eval( action['context'], eval_ctx ) or {}
  File "<string>", line 1, in <module>
NameError: name 'active_id' is not defined

Work around: Delete the "Unconfirmed registrations" dashboard element.
