Actually, it seems like it's intermittent. I just tested it again and could abort "properly" (yeah, there's surrenders), but trying it a second time caused the crash. Perhaps try aborting that mission a few times and see if it blows up?
On that note I had a crash earlier today when starting a Chupacabra Hunt mission, but that same mission started fine on the second attempt so sadly I can't provide you with a way to reproduce. But it's a data point so there you go.
[Edit] Attached the dump file for that crash in case it helps.
