Looks like it might be related to Ender Storage if I am reading it right. I would disable Ender Storage temporarily to see if that is causing the issue, and you can load your world. If it still crashes, that I am not quite sure.
Also, I'd use a different Java version. Latest version I've found that causes few, if any issues with FTB is 1.7.0_71
Lastly, might want to say what pack you are using. I see you are on 1.5.2, but still . Hope you figure out 1 way or the other!
