Can you check if without the patch, the crash happens with a new game? I think
this comes from the fact that you used a savegame from an earlier version, and
it couldn't find the map label in the error message.
The real solution is to make the terminal say something like:
"General security routine: Missing file: evil.conf. Will now exit.SIGSEGV"
And then lock the door leading to the underground pass. This will entirely
prevent the player from leaving the room until they happen to check the version
(which shouldn't be too painful). It will also prevent Bender from opening and
closing the door when patrolling in the room.
