Intersting Crash

[Karasu]

Hi all, i have found that i've run into a reproducable (for me) crash with FTB ultimate pack. Following the most recent update i have been constantly crashing whenever i enter the Multiplayer screen, before i can connect to servers, and i keep getting the same messages in console.
