Issues with jQuery 1.9 and slideToggle

Question

So, I'm not sure what happened, but I had its javascript function that shows / hides the div and then changes the + value to a - when it works.

This is what I have:

 $('.internal').hide();

$('.slider').click(function() {
    $(this).next('.internal').slideToggle();
}).toggle(function() {
    $(this).children("span").text("[-]");
}, function() {
    $(this).children("span").text("[+]");
    return false;
});

This seems to work fine with the jQuery 1.8 library, but when I switch it to 1.9 or higher, it just moves everything and makes everything unusable.

Not too sure what happened or what changed between 1.8 and 1.9, and I'm not sure what I need to fix for it to work again.

I made a fiddle: http://jsfiddle.net/9LcXk/

Uses 1.8.3 at the moment. But if you change it to 1.9 and run it, you will see what happens.

$('.slider').click(function () {
    $(this).next('.internal').slideToggle();
    this.toggle = !this.toggle;
    $(this).children("span").text(this.toggle ? "[-]" : "[+]");
    return false;
});
