I recently installed MinecraftForge, CodeChickenCore, and NotEnoughItems. One problem I have found is that when in creative mode and you click the 'chest icon' to see your inventory, my Minecraft crashes. Below I have included a link to the crash-report, Minecraft automatically creates when it has crashed, and the ForgeModLoader-client-0.log, in the .minecraft folder.

P.S. I have tried with every MinecraftForge version for Minecraft 1.5, it still seems to crash.
