[SciPy-user] blitz error

I tried this little bit of code:

def linear_p(qp_hat, qm_hat, vg, kappa, n1, il, ik):

	linp = np.zeros(qp_hat.shape) + 0.j
	expr = "linp = -vg * qp_hat * il + kappa * ik * n1 * qm_hat"
	weave.blitz(expr, check_size=1)
	return linp

and got the following error:

Traceback (most recent call last):

     k1p = filter(k1p) + linop_p(Ep_hat, Em_hat)

Could it be because I'm using complex numbers?
