I am very happy to report that this issue was fixed for me in patch 1.4. After hanging up my axe for several months and not playing Skyrim due to this bug, I loaded it up today when I learned 1.4 had been released. I had little hope, and expected a crash where the issue would still be present. I loaded my save inside Jorrvaskr and exited the doors. To my complete and utter joy, it loaded me into Whiterun instead of crashing to my desktop! Finally, I can play Skyrim again!

Exiting Jorrvaskr was my first 100% chance CTD. As I carried on playing, more and more doors caused 100% CTD, such as entering Understone Keep in Markarth, or even appoaching some places, such as Riften or the Dark Brotherhood sanctuary. The first 1.4 beta fixed all of my CTD issues.

Yea it was fixed by 1.4,at least they dropped the "you don't play normally so thats why you crash" line.
