Can confirm the crash.

CollectionChild->collection is NULL in that case
(and just continuing in case it is will later assert here BLI_assert(BLI_listbase_count(lb_scene) == BLI_listbase_count(lb_layer));)

I could do some further investigations, but I'm afraid that part of the code could end up being a time sink for me.

@brecht: could you take over? (feel free to throw back at me -- if it is OK that it might take some time to properly understand what's going on here)
