I just want to throw in that I'm getting this same crash behavior too with the latest download with the vanilla launcher and Multi-MC.
The vanilla launcher produces no error report.
There is no log in .minecraft/ForgeModLoader-client/server-x.log either.
I've never used forge before but I've been using Minecraft and mods since beta, I tried installing this 2 or 3 times making sure I followed all of the directions from a fresh download of 1.4.2, including deleting the META-INF folder.
If I go back one version then it works up until I try to generate a new world.
The only mod I was using with forge was the Twilight Woods mod in the mod folder, that seems to load OK.
Here are some screen shots:
Vanilla:
Here is the Multi MC report from the Generate Crash Report button (I bolded were it says jenkins in the report, I did read the EAQ but I downloaded the latest from http://adf.ly/673885/http://files.minecraftforge.net/minecraftforge-universal-latest.zip):
