Node material crashes Blender [2.59] (FIle enclosed)

I first created this node-based material in 2.49, aiming for a mountain range. I later upgraded to 2.59, tweaked it a bit, then found that when rendering, looking at the material in under the materials panel, or looking at the nodes would cause it to crash.

This, of course prevents me from fixing the problem.

Any advice of how to fix the problem?

Oh, honestly.

Does this blend crash ?

It doesn’t, actually. I don’t know how you did it, but thanks a million. That problems had been driving me insane. Was it an infinite loop or something like that?
