set_f_params error happens in integrate.complex_ode

[foxwb]

The example below was mainly copied from docs.scipy.org, and set_f_params worked well when the solver is integrate.ode, however, if changing ode to integrate.complex_ode, error happened when invoked set_f_params. The enviroment of Python is: Python3.4.3, Scipy0.15

from scipy.integrate import complex_ode
y0, t0 = [1.0j, 2.0], 0
def f(t, y, arg1):
     return [1j*arg1*y[0] + y[1], -arg1*y[1]**2]
def jac(t, y, arg1):
    return [[1j*arg1, 1], [0, -arg1*2*y[1]]]
#r = ode(f, jac).set_integrator('zvode', method='bdf')
r = complex_ode(f, jac)
r.set_initial_value(y0, t0).set_f_params(2.0).set_jac_params(2.0)
t1 = 10
dt = 1
while r.successful() and r.t < t1:
     r.integrate(r.t+dt)
     #print("%g %g" % (r.t, r.y))
     print(r.y);

Error message:
