New issue 2554 by asmeurer: Bug with sqrtdenest
http://code.google.com/p/sympy/issues/detail?id=2554

sqrt(2 + sqrt(2 + sqrt(2)))
((2**(1/2) + 2)**(1/2) + 2)**(1/2)
sqrtdenest(sqrt(2 + sqrt(2 + sqrt(2))))
nan

But the number is obviously not nan:

sqrt(2 + sqrt(2 + sqrt(2))).evalf()
1.96157056080646
