Hi Mark.

This sounds quite a lot like the problem described by Ciprian at 
http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2011-January/010611.html 
- you're not starting Rabbit in an unusual way are you?

If not, then this should definitely not be happening. Can you look in 
/var/log/rabbitmq/startup_log and see if the lines:

starting management agent                               ...done
starting management statistics database                 ...done

appear? Also, is there anything that looks error-like in the logs?

Cheers, Simon
