QtWebKit_bug_959 segfaults in all cases when PySide is built against Qt4.7 (at least)

According to http://alioth.debian.org/~odyx-guest/packages/pyside/pyside_1.1.1-1_analysis.txt and to past reports at http://bugs.pyside.org/show_bug.cgi?id=959 , this test segfaults for all python versions when PySide is built against Qt4.7.

https://launchpadlibrarian.net/102930935/buildlog_ubuntu-precise-amd64.pyside_1.1.1-1~p0_BUILDING.txt.gz suggests that it is similarly the case against Qt4.8, but is to be confirmed.

(It was already the case in 1.1.0 and is still the case in 1.1.1.)
