    Description

      Here is the SE_LineEditContents code from QMacStyle::subElementRect():

          case SE_LineEditContents:
        rect = QWindowsStyle::subElementRect(sr, opt, widget);
        if(widget->parentWidget() && qobject_cast<const QComboBox*>(widget->parentWidget()))
            rect.adjust(-1, -2, 0, 0);
        else
            rect.adjust(-1, 0, 0, +1);
        break;

      Note that it dereferences widget without checking for NULL.
