Askbot version:

$ git log -1
commit 777f5fc190780995f190473d8c567a14ca4d80f2

    fixed issue of conflicting migraions

Language settings in settings.py:

USE_I18N = True
LANGUAGE_CODE = 'en'

ASKBOT_LANGUAGE_MODE = 'url-lang'

LANGUAGES = (
    ('en', 'English'),
    ('zh', 'Chinese'),

ENABLE_HAYSTACK_SEARCH = True
HAYSTACK_ROUTERS = ['askbot.search.haystack.routers.LanguageRouter',]

Output of syncdb:

$ /usr/askbot-env/bin/python manage.py syncdb --noinput
System check identified some issues:

TypeError: 'NoneType' object has no attribute '__getitem__'

This seems to be related somehow to ASKBOT_LANGUAGE_MODE refactoring. The syncdb works well with single language setup, but haystack and multilang drops the exception above.
