Heyo,
Managed to find a repeatable crash, I've repeated it twice now.
Here's how it works:
My capital city; build merchant on far right tile. Next I click hut, and click on the tile next to it. The Hut graphic freezes without moving over to the construction graphic, and the whole game locks down. I alt tab out, and close the program. I reloaded my game, tried again, and the game froze again.
I have uploaded my save game and the dump. The city where this is happening is the far right city, and is also the capital.
