Message:

FE/Qt: bugref:7127: Improvement for UIMediumEnumerator: When some medium being unregistered we should enumerate it's first-level children to update their parent references; This is possible within snapshot tree architecture represented by differencing disks, while deleting snapshot having children.

Location:
