How can I get stage width of an loaded swf?

Question

Is there any way to get the real stageWidth of an loaded swf?
The problem comes when the loaded swf has some elements outside the scene. In this case content.width becomes bigger then the scene.
My code looks like this:
var request:URLRequest = new URLRequest(file.url);
var loader:Loader = new Loader();
loader.load(request);
loader.contentLoaderInfo.addEventListener(Event.INIT, checkSize);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, addImg);
private function checkSize(e:Event) {
            // this is where I need to see the width of my loaded swf
trace(e.target.content.width);
private function addImg(e:Event) {
                trace("complete");
Thanks,
Andrei

I don't think you can get the stage width of the loaded file unless you assign it as a constant somewhere within the file.  The loaded file forfeits its stage when it is loaded into another swf
