One difference there is that the "consumers" count on the overview page 
shows consumers from all vhosts, while "rabbitmqctl list_consumers" 
shows only the default vhost - do you only have one vhost?

Other than that, it is possible that the list of consumers in the 
management database has got out of sync with reality. I'd be interested 
to know how to repeat that.

Actually, looking at the code I can guess some possibilities. I don't 
suppose you had a crashing cluster node did you?

It's not a huge deal but I'd like to fix it.
