Opacity Animator crash when item is destroyed during animation

When using OpacityAnimator, if an item is destroyed while still animating, a crash will occur. If you replace OpacityAnimator with NumberAnimation with the opacity property, there is no crash.

Attached the core dump.

I've also attached a simple example of this for you to work with. It looks like m_target is not getting set to NULL when the item is destroyed. Therefore, QT is still trying to get it and use it.
