    Description

      Trying to render html via Qt5 QtWebKitWidgets QWebView causes the whole application to crash when the html uses javascript (MathJax) and includes some patterns with left/right quotes.

      To reproduce, use the attached python script that uses the python wrapper to QT5, together with the `test` html file that should be placed in the same directory. A web page is shown for some time, going from a fraction of seconds to some seconds, then one has a segmentation fault.

      All major browsers deal with this test html file nicely, so the issue seems to be confined to QT WebKit.
