Steps to reproduce:

• start Sugar

• open Log

• wait until one of the items on the Neighborhood View disappears (e.g. an Access Point is not in reach anymore), the important part is that you have not shown the Neighborhood View yet before the item is removed

A ​grid is added to the ViewContainer when the ​children are allocated. The allocation happens when the children needs to be shown. Therefore if the container and it's children have not been shown yet, ​removing the child from the grid will fail.
