OK. This is a functional example:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *
def itemSelected(self):
print "Selection changed"
app = QApplication(sys.argv)
grview = QGraphicsView()
scene = QGraphicsScene()
scene.addPixmap(QPixmap('on.png'))
grview.setScene(scene)
scene.selectionChanged.connect(itemSelected)
grview.show()
sys.exit(app.exec_())
It should run the function itemSelected and print "Selection changed" when I
click on the picture (little green square).

No, since you didn't provide a minimal example that I could try out or
provide more information on what exactly "doesn't work" means (is the
slot called at all for example). Its also not advisable to use the same
slot-function for both selection-changed signals since they have
different parameters and you'll need to write different code in each to
get the selected elements.
