OK, this is not the right solution, but I understand the issue.

QtFallbackWebPopup sets the parent of the combo to pageClient()->ownerWidget()

pageClient for the QGraphicsWebView is the QGraphicsWebViewPrivate, and
ownerWidget returns q->Scene()->views().value(0);

Now that is fixed for the lifetime of the QGraphicsWebView, so when you change
the scene that would have to be changed as well.

I still do not understand how hostWindow()->platformPageClient() becomes null.

Ah, that might be due to line 1785 in qwebpage.cpp:

    setView(qobject_cast<QWidget *>(parent)); 

I guess this should be 

QWebView* view = qobject_cast<QWebView*>(parent);
if (view) {
   // setView installs a proper page client for the QWebView, which is needed
   // for the Qt parts of WebCore to function proper.
   setView(view);
}

Would be nice if you could test this.
