Comment #8 on issue 1127 by [email protected]:
integrate(2*a/((((2*a)**2+x**2))**(3/2)),x) gives traceback
http://code.google.com/p/sympy/issues/detail?id=1127
This fails for a new reason (misuse of new_rawargs);
nsimplify(integrate(2*a/((((2*a)**2 + x**2))**1.5), x).n(2))
Traceback (most recent call last):
