      Description

      qstylesheetstyle.cpp line 4713 attempts to use w->parentWidget() when w is null (which is its default value).

      An example that is crashing for me is:

      QQuickStyleItem::pixelMetric() [line 1072] calls QStyleSheetStyle::pixelMetric() with:
      m = QStyle::PM_TabBarBaseOverlap
      w = null (default param)
