Exception in world tick - Server crashes everytime I log in

[Gwgallo]

The Tekkit server I play on crashed as I was in a portal to the nether a couple of days ago. The server had recently upgraded from 1.5.1 to 1.5.2. Every since the crash, everytime I try to log in it crashes the server. Others are playing at the time so not everyone is having this problem. I've attached a crash report. Any help would be greatly appreciated.
