It can't be V4, it would be nice and easy, but I got that message before she was even available, let alone installed.

There's nothing special about the killed file: it has V4, Ozone outfit, Shigi hair, Helena texture and morph plus the Condamned Hope freebie scene from DAZ, all coming from my main Poser 5 runtime on my external harddrive; the older files use things from various of my other runtimes, not just this one, but this one, too and seem to be fine.

I think it didn't save the scene correctly because of that XML error, not because something's causing trouble in it.
