I honestly have not even made it far enough in order to obtain summoning dolls. In the saved game I sent you, I'm currently exploring a dungeon in the Lv. 1 Battlefield. Just shift some of the items off my main character onto the DK (or from the DK to the main character) to overburden one of them to the point that it should way that it's "too heavy." For me at least, the game crashes.
Mind you, I am playing Beyond Divinity through the Steam client and I bought the digital copy from the Steam Store, so I don't know if that has any effect on why this is happening or the saved file's compatibility with your game.
