Problem with WebView loading specific web page

Question

I'm trying to develop an android app which accesses google wave. When I try to load this page (http://gwavefree.netau.net) the app just doesn't do anything and I get a blank screen. When I try to go to another site it works fine. Please help me!

Here is my full source code:

package co.uk.maxmarroni.apps;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;

public class GoogleWave extends Activity {
    /** Called when the activity is first created. */
    WebView webview;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        webview = (WebView) findViewById(R.id.webview);
        webview.getSettings().setJavaScriptEnabled(true);
        webview.loadUrl("http://gwavefree.netau.net");
    }
}

I'm only an android newbie so please be nice if its something easy to fix! :-)
