Nested loading not working in IE10

I made sure to grab the latest minified version of LazyLoad and test again before filing this issue.

I'm writing an application that does nested loading of JS files for development. I'm concatenating and minifying all those scripts into a single file for production. In development, this is what my LazyLoad loading looks like:

LazyLoad.js([
    './dev/js/lib/jquery.js',
    './dev/js/lib/json2.js',
    './dev/js/lib/swfobject.js',
    './dev/js/lib/web_socket.js'
], function(){
    LazyLoad.js([
        // dependent on jQuery
        './dev/js/lib/underscore/underscore.js',
        './dev/js/lib/backbone/backbone.js',

        // bootstrap modules
        './dev/js/lib/bootstrap/bootstrap-affix.js',
        './dev/js/lib/bootstrap/bootstrap-dropdown.js',
        './dev/js/lib/bootstrap/bootstrap-tooltip.js',
        './dev/js/lib/bootstrap/bootstrap-alert.js',
        './dev/js/lib/bootstrap/bootstrap-modal.js',
        './dev/js/lib/bootstrap/bootstrap-transition.js',
        './dev/js/lib/bootstrap/bootstrap-button.js',
        './dev/js/lib/bootstrap/bootstrap-popover.js',
        './dev/js/lib/bootstrap/bootstrap-typeahead.js',
        './dev/js/lib/bootstrap/bootstrap-carousel.js',
        './dev/js/lib/bootstrap/bootstrap-scrollspy.js',
        './dev/js/lib/bootstrap/bootstrap-collapse.js',
        './dev/js/lib/bootstrap/bootstrap-tab.js'
    ], function(){
        //LazyLoad.js([
            // backbone classes; not added yet
            //
        //], function(){
            LazyLoad.js('./dev/js/_script');
        //});
    });
});

The above works in all browsers except IE10. The first 4 files above load, then all loading stops. So, underscore and backbone and all the files that depend on them are not being loaded.

Oops. I just noticed there is a Pull Request for a version that fixes this issue (#13). I tested the code in that update. It's working properly in IE10.
