Django sqlite3 - an error when manage.py syncdb - django

Question

I can't overcome a problem with making new sqlite3 database under django 1.6 app. When I am doing python manage.py syncdb then it allows me to create some tables like:
Creating table django_admin_log
Creating table auth_permission
Creating table auth_group_permissions
Creating table auth_group
Creating table auth_user_groups
Creating table auth_user_user_permissions
Creating table auth_user
Creating table django_content_type
Creating table django_session
...but after some tracebacks it finish with an error:
Traceback (most recent call last):

My settings my include:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': 'database.db',
}
}
I don't know how to solve this problem. Could someone help me, please?

I assume you are using the hosting service of Alwaysdata because I Googled this problem and here is the same question on Alwaysdata's forum: Django sqlite3 - an error when manage.py syncdb.
The way I solve this problem is switching to a lower version of Django (e.g. 1.5.5) in my Alwaysdata admin page. Then the db file can be created successfully.
I still have not got the reason why this happens.
