Discussion add-in do not work

[franck.boisson@…]

I have instaled and enabled the Discussion plugin (fllowing ALL instructions) and now, when I try to access it, I have an error :

"Trac detected an internal error: no such column: forum_group.id"

My logs are:

13:03:07 Trac[api] DEBUG: SELECT id, name, description, (SELECT COUNT(id) FROM forum f WHERE f.forum_group = forum_group.id) FROM forum_group
13:03:07 Trac[main] ERROR: no such column: forum_group.id

DatabaseError: no such column: forum_group.id

Notice that I use a SQLite database and when I edit it with an explorer, I have all Discussion tables available and I can execute the last query printed on the log.
