Crash in QPainter::drawText on Mac

Draw text crash on Mac for the Monaco font when called with a non printable char like this:

    wchar_t wsz[] = { 0x00000012, 0x00000000 };
    QString str(QString::fromWCharArray(wsz, 1));
    painter.drawText(QPointF(50,50), str);

This used to create a square in previous versions.

Attached example application to reproduce.
