I guess there may be some red-light effect to it, but I'm really starting to feel like a great majority of crashes actually do happen when I'm sleeping, or out, or in some other weird situation where I'll miss that it happened. Sorry for the delay.
As for the bug itself, I didn't actually manage to find the root cause this time, so I still haven't fixed it. It seems that it should be rare enough that I don't expect to be constantly crashing on it. I'll keep debugging.
