Try deleting the files in the dynamic folder, then start a new game and save. Use
iZakaroN's SaveEditor to boost the constitution (etc), re-load, run to the thug camp and see if that causes a crash. If so, there may be a problem with the game itself, though a re-install usually helps then. If this works, there may be a problem in the saved game folder.
IIRC, you can just avoid that camp if all else fails. It is not related to a quest and there is nothing important there.
