ca.route automatic remove event deletes complete route. BUG?

Hi, can someone explain why can.route is removing every element from the active route, and the window.hash automatically after having added them?

1. // initialize can.route
2. can.route("#!:module/:sm1");
3. can.route.ready();
4. 
   
5. can.route.attr({
6.     module : "project",
7.     sm1 : "dashboard"
8. });

When binding to the "change" event of can.route with can.route.bind("change", .....), i always get "remove" events for module, sm1 and "route" itself.

In the browser, i can see "http://localhost:8080/#!project/dashboard" change to "http://localhost:8080/" automatically, with about 100ms of difference between them.

Tried it in both FF and IE.

What's causing this, is this normal?

Here is the jsFiddle for this: http://jsfiddle.net/BV7P6/4/

Appreciate your help!
