Comment #3 on issue 1863 by mattpap: nonlinear solver example stopped working
http://code.google.com/p/sympy/issues/detail?id=1863

Well, this is a bug, because solve() uses Groebner bases for solving polynomial systems and GB in SymPy can be computed only over a field. So, groebner() has to force coefficient domain change from integers ring to rational field, in this case. I fixed this problem in my local branch and currently working on more general solution.
