The error is symptomatic of a schema mismatch.

An upgrade of the server from 1.7.0 to 1.8.x should automatically move 
Rabbit's database to a backup location and start with a fresh one, since 
the schema changed between these versions. So I do not understand how 
any vhosts (or other data) can have survived the upgrade.

Does 'rabbitmqctl list_queues' show any queues? Ditto for exchanges, 
bindings and vhosts.

You may want to try resetting the db with
   rabbitmqctl stop_app
   rabbitmqctl reset
   rabbitmqctl start_app
