comma being added to result on series

[mcoolin]

self.requireTemplate = function(name, callbackn){
        _.series([
                function(callback){
                    self.waiton(false);
                    callback();
                    },
                function (callback) {
                    setTimeout(function () {
                        $.get('templates/'+name+'.htm', function(data){
                            self.waitoff(); 
                            callback(null, data);
                        }).error(function(e) { alert('Error: templates/'+name+'.htm not found'); });
                    }, 50);
                }],
            function(err, results){
                // getting an extra comma
                if(jQuery.isFunction(callbackn)==true){
                    callbackn(results);
                return;
            }  
        });
};

The callbackn(results) always has a "," prepended to the results.

Results appears to be a single string with result1 being null an appended coma and then result2. Instead of the expected Result1obj, result2obj2 as an array.

Failed to mention in my comment above that the expected data should have been:
[(null | empty object) , "some template"]
