There is a file called ForgeModLoader-server-0.log can you post that log instead after you have reproduced the crash?
 
Oh! I bet I know what this is... is mystcraft installed by any chance? If so then something was probably sent through the portal that wasn't a player. I have this problem on my server, if anything other than a player enters like a mob or an item/block it causes a crash.

There's a fix for this problem. I can't find the post where this was uploaded so I'll upload it here. Put this in the JAR OF THE SERVER, not the mods folder or the mystraft jar, ONLY THE SERVER needs to do this. Trust me it fixes it, at leased it did for me.
