      Description

      In recent versions of PySide (1.2.1 and 1.2.2), the Python object associated with child widgets are leaked if the parent widget is deleted.

      I have included an example that shows the Python garbage collector holding references to the deleted objects. shiboken.dump() confirms the C++ object was deleted.

      Widgets that PySide knows about:
      <PySide.QtGui.QWidget object at 0x7f5976c8f638>
      <PySide.QtGui.QDesktopWidget object at 0x7f5976c93560>
      The garbage collector knows about 32478 objects
      Found one: 140022221698616 <type 'PySide.QtGui.QWidget'>
      Found one: 140022221698832 <type 'PySide.QtGui.QLabel'>
      Found one: 140022221713920 <type 'PySide.QtGui.QLabel'>
