CException Alias "bootstrap.widgets.BsBreadCrumb" is invalid

[Cristian Astorino]

I'm trying to put a breadcrumb inside my page:

<?php $this->widget('bootstrap.widgets.BsBreadCrumb', array(
            'links'=>$this->breadcrumbs,
    )); ?>

but I obtain a CException saying Alias "bootstrap.widgets.BsBreadCrumb" is invalid. Make sure it points to an existing PHP file and the file is readable.

This is my config file: http://pastebin.com/p3W2XB6x
