Occasionally (in an indeterminate manner) an application using WebKit will crash with the following stack trace:

This appears to occur when navigating away from a page that contains CSS (even if there is no explicit media query). In this case, the application (Google Earth) is using QtWebKit (4.6.3) and navigating to "about:blank", but I do not think this is a Qt-specific bug.
