PySide pickle support
Is there a list of Qt classes that pickle?
I found this old thread about "PyQt support for pickling":http://www.riverbankcomputing.com/pipermail/pyqt/2007-April/016000.html.
Alternatively, is there a way to make pickling verbose? For example, I tried to pickle a QPixmap: it didn't throw any exceptions but it didn't produce expected results either.
