[PyKDE] PyQt4: Problems with QImage.loadFromData(data)

[com at heuel.org]

Dear all

I would like to use the function loadFromData of QImage, specifically
with PIL. But the code

[...]
        imagePIL = Image.open(fileName)       # e.g. a PNG file
        data = self.imagePIL.tostring()            # this should
contain the data

        image = QtGui.QImage()
        image.loadFromData(data)

[...]

Why doesn't this work?
