Weird exception on createHttpBackend when doing an $http.get

I'm just getting started on AngularJS and for some reason I'm having a problem. I'm running an http get query to the Last.fm API in order to retrieve similar artists to Caravan. I have tried the query on a web browser and it returns the correct XML response.

This is my controller:

function ArtistsCtrl($scope, $http) {
    //artist: $scope.artist;
    $scope.getArtists = function() {
        $http.get('http://ws.audioscrobbler.com/2.0/?method=artist.getsimilar&artist=Caravan&api_key=MY_API_KEY').success(function(data) {
            echo(data);
        }).error(function(data, status, headers, config){
            echo(data);
        });
    };
};

And this is my view:

<!doctype html>
<html lang="en" ng-app>
<head>
<meta charset="utf-8">
<title>My HTML File</title>
<link rel="stylesheet" href="css/app.css">
<link rel="stylesheet" href="css/bootstrap.css">
</head>
<body>
    <div ng-controller="ArtistsCtrl">
        <button ng-click="getArtists()">Get artists</button>
    </div>
    <script src="angular.js"></script>
    <script src="angular-resources.js"></script>
    <script src="app.js"></script>
</body>
</html>

The problem is that when I click on the button and it executes $http.get, it throws the following exception and never returns any data.

[Exception... ""  nsresult: "0x805e0006 (<unknown>)"  location: "JS frame :: http://localhost/AngularJS/angular.js :: createHttpBackend/< :: line 9409"  data: no]
http://localhost/AngularJS/angular.js
Line 5764

Anyone has any idea about what could be the problem? Thanks.

Tried downloading AngularJS 1.0.5 and it worked fine, it gives me the error on 1.1.3 .
