Don't crash via proxy model when moving QModelIndexes
The layoutAboutToBeChanged signal gives proxies a chance to persist QModelIndexes. The d->itemsAboutToBeMoved method is part of the process of moving the persistent indexes. d->itemsAboutToBeMoved must be called after layoutAboutToBeChanged. Otherwise persistent indexes will not be updated. Merge-request: 2219 Reviewed-by: Olivier Goffart <ogoffart@trolltech.com>
