Cancelling angular $http.jsonp results in javascript error

I'm using Angular version 1.2.1 and I'm attempting to implement cancelation in my application when a new request of the same type is initialized. I used the code examples here but I couldn't get it to work. I think this is due to the fact that I am using $http.jsonp().

When I cancel a jsonp request the .then callbacks are never called (as expected) but the request is not cancelled and when the response comes I get an undefined error in the console (the jsonp callback function no longer exists).

How do I avoid getting this console error? Is it possible to cancel a jsonp request alltogheter?

HTML:

<div ng-controller="MyCtrl">
    <span ng-bind="status"></span>
    <hr>
    <a href ng-click="doStuff()">
        Start
    </a>
    <hr>
    <a href ng-click="cancel()">
        Cancel
    </a>
</div>

JS:

var myApp = angular.module('myApp',[]);
function MyCtrl($scope, $q, $http) {
    $scope.status = "Idle";

    $scope.doStuff = function() {
        var canceller = $q.defer();
        $scope.status = "Ongoing";
        $scope.getting = $http.jsonp('http://cruisebookingapi.ving.se/cruisePackage/search/1/STO/141220/false/20141211/42,42/-1?callback=JSON_CALLBACK', {timeout: canceller.promise});
       $scope.getting.then(function(data) {
            $scope.status = "Finished";
            console.log(data);
        });
        $scope.cancel = function() {
            $scope.status = "Cancelled";
            canceller.resolve('Cancel all the things');
        };
    };
}
