Gtk Viewport adds a 2px border

Hello

I'm currently trying to put together a simple text editor using Vala, just for learning.
In this text editor I have a Label which contains the line numbers and a TextView which is the editor itself, these two are inside Box.

Since I want to allow scrolling I've put the box inside a Viewport since the Box isn't a scrollable widget and then I've put the Viewport inside a ScrolledWindow.

My Code looks like this:

var hbox = new Box(Orientation.HORIZONTAL, 0);
var viewport = new Viewport(null, null);
var scroll = new ScrolledWindow(null, null);

hbox.pack_start(line_numbers, false, true, 0);
hbox.pack_start(this, true, true, 0);

viewport.add(hbox);

scroll.set_policy(PolicyType.AUTOMATIC, PolicyType.AUTOMATIC);
scroll.add(viewport);

The problem is that a get a 2px space around the Box when using the Viewport, if I remove the Viewport the space disappears but then scrolling won't work.
Anyone have any idea why the viewport adds this space and how to get rid of it?

Thanks
