That's weird, you are getting a conflict error on inserting the root
application object (oid 0x00).

So for some reason the startup code cannot load the existing root
object, thinks the database is empty and tries to start fresh. I'm not
sure how that could happen, unless the ZODB connection strings are
wrong or database permissions not quite right.
