That's weird. I just tried the fight in the first dialogue choice several times, but it wouldn't crash for me. Does it crash every time for you, or is it random?
It just crashed the first time, the second time I could finish it. My theory is that the Full-screen-Mode is to blame. I play the game all the time in Full-screen but make my screenshots in windowed mode because for some reason I can't make screenshots of the game in Full-screen.
