Can confirm, will check

Well, that file should not crash on its own, but noticed that the library //../2019/source.blend is missing.
Can you provide that as well?
Does it still crash if this is located where expected?

Yes, it also crashes if the source.blend is available. This is from a larger project that crashed on opening, so I took out everything I could while keeping the crash.
Here I removed everything from source.blend but the linked mesh and merged it down to one point (hope it's still helpful in this state):

@mont29: for some reason we have a proxy_group on the object, but that in turn has a NULL instance_collection (thus the crash)
Maybe that is_override_instancing_object should check more? (looks like we should/could actually use ob_proxy->proxy->id instead?
