This is not a known issue, but there was a similar problem reported awhile ago, where the game would crash after the troll king froze the character. They restarted the game, and did not encounter the problem again.
For some reason getting the quest to kill the trolls is exacerbating the problem with that area. <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
