Exception in computing u0 for the KuzminKutuzovStaeckelPotential

Reported by @wilmatrick

#import packages:
import numpy
from galpy.potential import KuzminKutuzovStaeckelPotential
from galpy.actionAngle import actionAngleStaeckelGrid

#potential parameters:
Delta = 0.27876  #focal length of (lambda,nu) coordinate system
ac    = 61.9673  #axis ratio of coordinate surfaces of disk component

#setup two components, disk and halo, potentials (already normalized):
pot = KuzminKutuzovStaeckelPotential(ac=ac,Delta=Delta,normalize=True)
#setup action angle object:
aA = actionAngleStaeckelGrid(pot=pot,delta=Delta,Rmax=5.,
                                                 nE=25,npsi=25,nLz=30,numcores=1,c=True)

This fails, because of a failure in
