TypeError: coercing to Unicode: need string or buffer, NoneType found

Hello,

I thank you for the plugin in django-cms.

I have installed the version 0.6.3. I was the problem for the indexation with the command django: rebuild_index

The problem come here : text += obj.get_meta_keywords() if hasattr(obj, 'get_meta_keywords') else u'' in search_indexes.py.

I replace this line by text += obj.get_meta_keywords() or u''
It's good after.

Thanks.

I can confirm this:

Test with
text += obj.get_meta_keywords() or u''

Hello,

The same for me:

python manage.py rebuild_index --settings=demo.settings.local

Had the same problem. Changing the line to text += obj.get_meta_keywords() if hasattr(obj, 'get_meta_keywords') else u'' fixed it for me.
