Interesting - that suggests that something went wrong when upgrading the
data store on disk from a previous version of Rabbit. If you can locate
where Rabbit is storing files on disk - usually given in the successful
startup of Rabbit - and can pack up the files and send them to us (off
list), I'm sure we'd like to take a look at that to try and figure out
what went wrong.

Once you've taken a copy of those files, you can delete all those files,
and Rabbit will start up fine, but it'll start up with a fresh state and
will have forgotten all messages/queues/exchanges/bindings/vhosts/users
that it had saved (if any).
