I think...something's corrupting your world...possibly to do with extrautilities?. Try loading it in mcedit and editing out the problematic block/chunk:
Details:
Found chunk: true
Location: World: (-1091,82,-812), Chunk: (at 13,5,4 in -69,-51; contains blocks -1104,0,-816 to -1089,255,-801), Region: (-3,-2; contains chunks -96,-64 to -65,-33, blocks -1536,0,-1024 to -1025,255,-513)
there was a problem getting a block type. I don't really know about this but maybe you uninstalled a mod and now the game crashes when minecraft tries to load one of its blocks? If so then try re-installing the mod.
