linkClickedシグナルを発行するには、リンク委任ポリシーを適切に設定する必要があります。

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_())
