factor(expand((sin(x)+sin(y))*(cos(x)+cos(y fails
http://code.google.com/p/sympy/issues/detail?id=1355
This is really a duplicate, works now, e.g.:
In [1]: e = (sin(x)+

Of course, it works in the new polys:
In [3]: factor(expand((sin(x)+sin(y))*(cos(x)+cos(y
Out[3]: (cos(x) +

I made a mistake. Sage can do it:
sage: e = (sin(x)+sin(y))*(cos(x)+cos(y))
sage: factor(expand(e))
(cos(y) + cos(x))*(sin(y) + sin(x))
sage: e

http://code.google.com/p/sympy/issues/detail?id=1355
Sage also can't do it, but at least it doesn't raise an exception:
vasage: var("x y")
(x, y)
sage: e = (sin(x)+sin(y)*(cos(x)+cos(y)))
sage: e

In [2]: e = (sin(x)+sin(y)*(cos(x)+cos(y)))
In [3]: e
Out[3]: (cos(x) + cos(y))â‹…sin(y) +
