P1: Critical Description
Open the attached project in Design Studio. Multiselect light and either camera or cube or all three from navigator and press delete key. All qmlpuppets crash (in release mode this causes brief flicker on them as they quietly restart, but in debug mode you get crash notification dialogs).
Single deleting the light doesn't crash, so it seems that somehow the light gets added to dirty list because of the other items included in same deletion, and then the light itself gets deleted before dirty list is handled, leaving a deleted light pointer in the dirty list.
