Crash when calling mapToItem on QML Flickable's contentItem

    Description

      Trying to align a rectangle with the current item inside a ListView, I discovered that qt would segfault whenever I called mapToItem on the listview's contentItem.

      Backtracing I see that this is caused by QDeclarativeEngine::contextForObject(ptr_to_listViewContentItem) returning 0, which is dereferenced in QDeclarativeItem::mapToItem.

      See the attached minimal example.
