Ditto for 3.0.2.

In makeviewpart.cpp, we have:
  MakeViewPart::MakeViewPart(QObject *parent, const char *name,
  const QStringList &)
      : KDevMakeFrontend("MakeOutput", "makeoutput", parent, name)
  {
      setInstance(OutputViewsFactory::instance());

      setXMLFile("kdevmakeview.rc");

Turns out OutputViewsFactory::instance() == 0x0. Any ideas why?
