#015313: Can't have a dot in URL variable anymore with ezcMvcRailsRoute ?

I resume the development of an application that uses the MvcTools. In this application, I defined the following route :
/topic/list/:newsgroup_name where :newsgroup_name is the name of a newsgroup so it can be something with a lot of dots, for example foo.bar.ezc.is.cool :)

With eZ Components 2008.2, everything went fine, the URL /topic/list/foo.bar.ezc.is.cool works as expected but with eZ Components 2009.1.1, no route is found with the same URL.

In addition, with eZ Components 2009.1.1, if a parameter value has only one dot, the matching is wrong. For instance, with the URL /topic/list/foo.bar, newsgroup_name contains only "foo".

It seems that this regression was introduced in the rev 10130 [1].
