QWebKit Signal Not Activated

import sys

from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtWebKit import QWebView

app = QApplication(sys.argv)
web_view = QWebView()
def url_changed(url):  print 'url changed: ', url
def link_clicked(url):  print 'link clicked: ', url
def load_started():  print 'load started'
def load_finished(ok):  print 'load finished, ok: ', ok
web_view.connect(web_view, SIGNAL("urlChanged(const QUrl&)"), url_changed)
web_view.connect(web_view, SIGNAL("linkClicked(const QUrl&)"), link_clicked)
web_view.connect(web_view, SIGNAL('loadStarted()'), load_started)
web_view.connect(web_view, SIGNAL('loadFinished(bool)'), load_finished)
web_view.load(QUrl('http://google.com'))
web_view.show()
sys.exit(app.exec_())

The linkClicked signal does not work. Other signals work. Qt 4.6.2 in Win XP.

Policy The link delegation policy must be correctly set for the linkClicked to be emitted.

import sys

from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtWebKit import QWebPage, QWebView

app = QApplication(sys.argv)
web_view = QWebView()
web_view.page().setLinkDelegationPolicy(QWebPage.DelegateAllLinks)
def url_changed(url):  print 'url changed: ', url
def link_clicked(url):  print 'link clicked: ', url
def load_started():  print 'load started'
def load_finished(ok):  print 'load finished, ok: ', ok
web_view.connect(web_view, SIGNAL("urlChanged(const QUrl&)"), url_changed)
web_view.connect(web_view, SIGNAL("linkClicked(const QUrl&)"), link_clicked)
web_view.connect(web_view, SIGNAL('loadStarted()'), load_started)
web_view.connect(web_view, SIGNAL('loadFinished(bool)'), load_finished)
web_view.load(QUrl('http://google.com'))
web_view.show()
sys.exit(app.exec_())
