Error Tracing

Other than the show err command, is there any other way of tracing errors? I am getting a random CTD, which I believe is related to character names. I am putting completely new names in for all factions, and its all going fine until now. It can play for 30/40 turns and then crash. Only happens when I am recruiting a named agent (or possibly a female birth). There is nothing obvious in the various names files - they all seem to match. I must have overlooked something obvious, and the show err reveals nothing as it crashes to desktop! Anything available to elp before my brain dries up?
