This was a problem with the enthought.persistence.state_pickler
module. It was not handling numpy.float32 (or similar) objects and
was pickling those values as None. I've fixed this (and tested for
it) in a new maintenance branch of enthought.persistence in the
branches:
https://svn.enthought.com/enthought/browser/branches
The fix is a trivial 2 line patch.
https://svn.enthought.com/enthought/changeset/14006
So you can either get the branches and install the new version or
apply the patch to your install.
cheers,
