Hmm, this is a weird one. The overview code is really simple: it gets a
list of all queues, retrieves message statistics for them, and then sums
them. It really should not be able to count messages if there are no queues.
I wonder whether this was a caching issue at the HTTP level or something.
Of course, if you have a way to reproduce this I'm anxious to hear of it.
