When I try to generate this seed in 1.4.2 : "4620173850137257062", Minecraft freezes.

Whenever I try to generate this seed:
4620173850137257062

Minecraft freezes, and becomes unresponsive. After I reopen Minecraft, the world appears at the worlds screen, but if I try to access it, same thing happens. Minecraft freezes.

This seed should have been a nice mountain seed.

Steps:
Open Minecraft
New world
Put in this seed 4620173850137257062
Freeze.
