Comment #3 on issue 1260 by ondrej.certik: the solver fix broke python
-Qnew tests
http://code.google.com/p/sympy/issues/detail?id=1260
If you apply the following patch, it will also fail in regular python
(without
-Qnew), so I think this is not related to Robert's patch above, but rather
it's a new
bug.
