Django syncdb exception after updating to 1.4

So I was developing an app in Django and needed a function from the 1.4 version so I decided to update.
But then a weird error appeared when I wanted to do syncdb
I am using the new manage.py and as You can see it makes some of the tables but then fails :

./manage.py syncdb
Creating tables ...
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_user_permissions
Creating table auth_user_groups
Creating table auth_user
Creating table django_content_type
Creating table django_session
Creating table django_site

TypeError: db_type() got an unexpected keyword argument 'connection'

I had the same issue, the definition for my custom field was missing the connection parameter.

from django.db import models

class BigIntegerField(models.IntegerField):
    def db_type(self, connection):
        return "bigint"
