I'm using Qt 4.8 beta1 and the version of QtWebKit that comes with it (2.2 beta).
When calling page() in a subclass of QGraphicsWebView to get the page, QtWebKit instantiates it and deadlocks with this backtrace:
__semwait_signal + 10 (in libSystem.B.dylib) [0x7fff87503a6a]
QWaitCondition::wait(QMutex*, unsigned long) + 304 (in QtCore) [0x103004d40]

QMetaObject::invokeMethod(QObject*, char const*, Qt::ConnectionType, QGenericReturnArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument, QGenericArgument) + 1324 (in QtCore) [0x103120f6c]

ContentView::ContentView(QGraphicsItem*) + 251 (in testprogram) [0x1000178ab]
In this backtrace, page() was called from setHtml() but it also happens if I call it directly or indirectly by using other methods such as settings().
