Default route is matched instead specific route

Question

<routes>
    <www type="Zend_Controller_Router_Route_Hostname">
        <route>www.domain.com</route>
        <chains>
            <index type="Zend_Controller_Router_Route">
                <route></route>
                <defaults module="default" controller="index" action="index" />
            </index>
            <community>
                <route>community</route>
                <defaults module="community" />
                <chains>
                    <index type="Zend_Controller_Router_Route">
                        <route>:action/*</route>
                        <defaults controller="index" action="index" />
                    </index>
                    <member type="Zend_Controller_Router_Route_Regex">
                        <route>member/profile-(\d+)-(.+)</route>
                        <reverse>member/profile-%d-%s</reverse>
                        <map>
                            <id>1</id>
                            <nom>2</nom>
                        </map>
                        <defaults action="viewmember" />
                    </member>
                </chains>
            </community>
        </chains>
    </www>

As you can see, I use a route with :action/* in to cover the homepages and the basics actions on index controller.

domain.com/community/random_action => works good.

domain.com/community/ doesn't work. The whole homepage is displayed. I checked, and the default route is matched.

I tried assemble() on route "www-community-index" and it gives well www.domain.com/community

I don't see from where comes the problem :(
