You cannot instantiate a base class wrapped through sip with super. You need
to directly call the base class contructor via the __init__ method.
I quote "The way that super is currently implemented means that the lazy
lookup is bypassed resulting in AttributeError exceptions unless the
attribute has been previously referenced."
I don't advocate the use of super, because while it might save some typing,
you end up introducing weird bugs like these into your program. Just call
the base classes __init__ method directly instead.
