I am not sure why nil is passed to <=>, but I think the following patch should fix the problem.
diff --git a/app/models/enumeration.rb b/app/models/enumeration.rb

I think the data in your database is inconsistent. For example, you deleted document categories by directly using a DELETE statement of SQL. I succeeded to reproduce the error by deleting document categories with the following SQL.
delete from enumerations where type = 'DocumentCategory';
The attached patch fixes the issue by ignoring inconsistent data.
