PyQT open a web page with JS alert pop up will get SegFault. How to fix that?

javascript python qt4 pyqt

This works with the test case given above for

Qt:     4.7.2PyQt:   4.8.3 or PySide 1.0.1Python: 2.7.1

As noted above in the comments, http://developer.qt.nokia.com/forums/viewthread/4760 explains the bug and it is reported as fixed from https://bugs.webkit.org/show_bug.cgi?id=57414 and was probably included in Qt 4.7.2.
