How to enable ScrumBurndownPlugin in 0.11b1

[anonymous]

I recevied these error messages, after I enabled ScrumBurndownPlugin component in trac.ini file and execute trac-admin ./project-name upgrade.

Traceback (most recent call last):
  File "/.../bin/trac-admin", line 7, in ?
    sys.exit(

Who knows what's going on here?

I found putting a db.commt(); in burndown/burndown.py works. i.e., make it like so:

    def upgrade_environment(self, db):
        cursor = db.cursor()

        needsCreate = False
        try:
            cursor.execute('SELECT * FROM burndown LIMIT 1')
        except:
            needsCreate = True
        db.commit();
