New issue 2939 by [email protected]: Solve with expressions containing infinity fails
http://code.google.com/p/sympy/issues/detail?id=2939

Solve is failing for me even on some relatively simple expressions containing infinity. The errors appear to be polys related.

In [1]: solve(x+oo, x)
Out[1]: [-∞]

In [2]: solve(x-y+oo, x)
CoercionFailed: expected `Rational` object, got -oo

sympy/polys/domains/pythonrationalfield.pyc in from_sympy(self, a)
