has_traits.py:1536: FutureWarning: comparison to `None`

[xaverm]

Executing this snippet

# block 1
%pylab inline
%gui wx
from mayavi import mlab as ml

# block 2
def egr(x,y):
    return cos(x)+cos(y)
N=300
x,y = mgrid[-2*pi:2*pi:N*1j,-2*pi:2*pi:N*1j]
z = egr(x,y)

# block 3
ml.figure()
ml.surf(x,y,z,warp_scale=2);

as the very 1st in an ipython notebook produces this:
from block 1
WARNING:traits.has_traits:DEPRECATED: traits.has_traits.wrapped_class, 'the 'implements' class advisor has been deprecated. Use the 'provides' class decorator.
from block 3
/home/JohnDoe/temporary/ets/traits/traits/has_traits.py:1536: FutureWarning: comparison toNonewill result in an elementwise object comparison in the future. setattr( self, name, value )

The deprecation waring from block 1 has already been posted in the open issue [link to https://github.com//issues/143]

These warnings occurred after an upgrade of my systems IPython from a 1.x version to a 2.x version.

IPython 2.2.0
