I don't think it's the crypt door that's causing the CTD exactly, if you attempt to move around in Dromed near the crypt door yes the game crashes but if you look at the monolog before you try to open the crypt door (whilst in that same room) you'll see 100's of meta-properties of 'bad cret pos' for Bart, and quite a few for most of the other AI's you've KO'd, but I can't see what is causing this to occur. Whatever the cause the attempt at opening the crypt door is causing an overload.
Bart is linked to a TSButton 2641 which is the trigger for loads of AI's, and if you load some of these AI's in Dromed that can also cause CTD, but which one specifically is causing the CTD if it's not Bart is beyond my Droming skills.
I'll PM Nicked as it's his mission and post your CTD on Shadowbox.
