I will add that the remaining issue is: http://paste.debian.net/22474/

The generated sipQtWebKitWidgetspart8.cpp has this line:

typedef void (*sipVH_QtWidgets_116)(sip_gilstate_t,
sipVirtErrorHandlerFunc, sipSimpleWrapper *, PyObject *, double
*,double *,double *,double *);

I guess this is a bug in sip, there should be qreal's there (as
defined in qgraphicswidget.sip).
