Issue with navigation in sammyJS javascript plugin?

Question

I am using sammy.js plugin in my single page application. The plugin is not working, whenever user tries to navigate in the page it is showing the following error on console :

[Tue Dec 04 2012 17:48:13 GMT+0530 (India Standard Time)] #main 404 Not Found get /page_home  
Error
arguments: undefined
get stack: function () { [native code] }
message: "404 Not Found get /page_home "
set stack: function () { [native code] }
type: undefined
__proto__: d

What is this issue and how can it be fixed ?

EDIT

Sammy configuration code:

 var app = $.sammy('#main', function () {
        this.get('#/:name', function () {
            var id = this.params['name'];
            $.trim(id);
            var flag = true;

            if ($("#main").hasClass("presentation")) {
                $.each(slides, function (i, v) {
                    if ($(v).attr("class") == id) {
                        ScanNavigationD(id);
                        flag = false;
                        return false;
                    }
                });
                if (flag) {
                    ScanNavigationD($(slides[0]).attr("class"));
                }
            }
            else if ($("#main").hasClass("printdoc") || typeof $("#main").attr("class") == "undefined") {
                $.each(Pages, function (i, v) {
                    if ($(v).attr("class") == id) {
                        ScanNavigationD(id);
                        flag = false;
                        return false;
                    }
                });
                if (flag) {
                    ScanNavigationD($(Pages[0]).attr("class"));
                }
            }
        });
    });

    $(function () {
        app.run();
    });

@tom-rider the problem is the app.run called without argument. The sammy app.run function accept a start_url argument to set (via the _setLocation method) the app current location before call _checkLocation method to check if url is changed... So try to change

app.run();

with

app.run('#/');

this work for me.

Follow this fiddle for a working demo and look at the console: no error!
