Starting Mozilla from XPCShell

[David Olivari]

I'd like to open a window from xpcshell under Linux :

var AppShellClass = 
Components.classes['@mozilla.org/appshell/appShellService;1'];

var AppShellObj = 
AppShellClass.getService(Components.interfaces.nsIAppShellService);

var CmdLineClass = 
Components.classesByID['{e34783f5-ac08-11d2-8d19-00805fc2500c}'];

var CmdLineObj = 
CmdLineClass.getService(Components.interfaces.nsICmdLineService);

var URLClass = Components.classes['@mozilla.org/network/standard-url;1'];

var URLObj =
URLClass.createInstance(Components.interfaces.nsIURL);

URLObj.scheme="file";
URLObj.path="/tmp/test.xul";

var test = Components.interfaces.nsIXULWindow;

AppShellObj.CreateTopLevelWindow(null,
                URLObj,
        true,
        false,
        Components.interfaces.nsIWebBrowserChrome.CHROME_ALL,
        640,480,
        test);

And then I get this :

Any Idea
