As feared, a few hours of poking the code hasn't thrown up any dirt.

Do you still have the rabbit.log file from around the time of the crash? 
If so, please send it to us.

Also, it would be useful to get some more details on how you are using 

How many queues are there? How much queue churn is there (i.e. queues 
being created and deleted)?

Do published messages only ever get routed to a single queue or can they 
get routed to multiple queues?

How big are the messages?

How long (#messages) are the queues, and how does that figure change 
over time?
