Node properties not created when using neo4django

I have a Model in django created with neo4django.

class Person(models.NodeModel):
    """
    Persons of a Company
    """
    email = models.EmailProperty(required=True, unique=True, indexed=True,
                                 name=_(u'email'),
                                 verbose_name=_(u'person email address'),
                                 help_text=_(u'bla bla bla some help text'))
    full_name = models.StringProperty(name=_(u'Person full name'))

    # Neo4J Relationships
    role = models.Relationship(Role, rel_type='has_role',
                                     direction='Outgoing',
                                     related_name='persons')
    company = models.Relationship(Company, rel_type='works_to',
                                           direction='Outgoing',
                                           related_name='employees')

I try on the django shell

>>> p = Person.objects.create(email=u'[email protected]')
>>> p.id
6
>>> Person.objects.get(id='6')
<Person: Person object>
>>> Person.objects.get(email=u'[email protected]')
Traceback [bla bla bla]
[...]
DoesNotExist: Person matching query does not exist.
>>>

I also checked on the Neo4J web interface and I see the created node, but without any properties!

This problem looks like the one mentioned here but I am not sure if this is the same issue.

I have Django 1.4.5 and Neo4J 1.8.2

Matt thanks a lot for your recommendation. I always run the master git version.

I upgraded to Django 1.5.1 and the problem disappeared. I still run the 1.8.2 version of Neo4J.

UPDATE

Trying to figure it out, I reverted back to Django 1.4.5 and after some research, I discovered, that the problem was actually because of the name attribute on the node properties.

So if I change this 

full_name = models.StringProperty(name=_(u'Person full name'))

to this 

full_name = models.StringProperty(verbose_name=_(u'Person full name'))

or this

full_name = models.StringProperty()

then everything works as expected.

Actually the name issue exists even if you upgrade to Django 1.5.1 so I guess there is some issue creating the properties when having a name attribute in it.

What version of neo4django are you using? I'd suggest trying the same code with neo4django master off Github (pip install -e git+https://github.com/scholrly/neo4django#egg=neo4django-dev).
