Route ZF1

[Douglas Lira]

Estou com um problema e não consigo identificar o erro.

No bootstrap em _initRouter() tenho:

$slugRouter = new Zend_Controller_Router_Route(':slug', array('module'=> 'default', 'controller' => 'busca', 'action' => 'perfil'), array('slug' => '\w+'));
$router->addRoute('slug', $slugRouter);

na minha index.phtml tenho:

href="<?php echo $this->url(array('slug' => 'casa-arte'), 'slug'); ?>"

Porem quando clico na URL recebo o seguinte erro:

An error occurred
Application error
Exception information:
Message: slug is not specified
