[PySide] sending data from urllib2.urlopen().read() via signal corrupts in receiver

I am downloading a few images in a separate thread using QRunnable.
To download I am just using urllib2.urlopen() like this:

     def run(self):
         imageData = urllib2.urlopen(self.url).read()
         print 'emitted:', imageData
         self.signals.receivedData.emit(imageData) # this signal is 
declared like this: QtCore.Signal(str)

However, the receiving slot is receiving nothing:

     def setPixmap(self, imageData):
         print 'received:', imageData
         pixmap = QtGui.QPixmap()
         self.data['pixmap'] = pixmap

I guess this is too naive an approach to download image data in a 
separate thread?!

How can I fix this please?
