Could you please provide some more details steps on how to reproduce this crash. Looking at the backtrace it looks similar to bug 1205010, which can be triggered by dismantling either a conquered military building or dismantling one of the pre-existing ones in a campaign map. If this sounds like your issue, it is likely a duplicate, otherwise we will need more information to investigate further.
