Just assigning weights to vertices.
I can't seem to get precise repro steps for this.
But it involves using the Weights tool, then using CTRL+drag to select vertices. It usually (and easily) crashes when the selection box hits a first vertex. But sometimes it doesn't. I suspect it has something to do with what was selected already.
