You can cause the game to crash using the BUY/SELL interface. Select an item to sell in which you have many of. Then select another item that you have LESS of. Use the sell button. The game will crash and cause an error message. When selecting a new item from the list it should either default back to 1 or to the count of that item. It should not stay at the max count of the other item.

I fixed it resetting the quantity to 0, thank you for the advice.

I think when possible (ie, you have enough money in case of the buy dialog), the quantity should be reset to 1 and not to 0. This way you wouldn't have to click the + button and you could even just press Buy several times to buy multiple of the same kind.
