qt-bugs@ issue : N199058
Trolltech task ID : 199428 (Status: closed; Version fix: 4.4.0)
applied: no
author: Frerich Raabe <raabe@kde.org>
Fixes a crash in QGraphicsProxyWidget which was triggered when no
QGraphicsProxyWidget item in a QGraphicsScene had a QWidget associated
with it. As soon as the user pressed <Tab>, QGraphicsProxyWidget
attempted to give the focus to *some* QWidget (even if it was null).
