fancybrowser can't run test262

1. Start fancybrowser example
2. Go to http://test262.ecmascript.org/
3. Click the Run tab
4. Next to "Chapter - ch06 (1 tests)" click Run

After clicking Run, the test never runs. It works fine in Qt 4.8.2.
If "view->page()>mainFrame()>evaluateJavaScript(jQuery);" is commented out in MainWindow::finishLoading(), the test runs fine.

It works fine in the Qt Demo Browser example.
