AttributeError: TextWithDash instance has no attribute '_mytext'

Hi all,

I tried to reproduce the Contour3D plot

from numpy import *
import pylab as p
import mpl3d.mplot3d as p3

# in mplt3D change:
# levels, colls = self.contour(X, Y, Z, 20)
# to:
# C = self.contour(X, Y, Z, *args, **kwargs)
# levels, colls = (C.levels, C.collections)

delta = 0.025
x = arange(-3.0, 3.0, delta)
y = arange(-2.0, 2.0, delta)
X, Y = p.meshgrid(x, y)
Z1 = p.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
Z2 = p.bivariate_normal(X, Y, 1.5, 0.5, 1, 1)
# difference of Gaussians
Z = 10.0 * (Z2 - Z1)
ax = p3.Axes3D(fig)
