Be aware that PySide has a bug regarding QGenericArgument and
QGenericReturnArgument.
The default constructor does not work.
I already filled the issue with a workaround half a year ago:
https://bugreports.qt-project.org/browse/PYSIDE-76
You can either patch your PySide installation or avoid using these two classes
without arguments.
