I think I can spot a pattern here ...

I am pretty sure the problem stems from the removal of a mis-feature in 
Erlang R212B-5 that the RabbitMQ server 1.4.0 is depending on, namely

     OTP-7524  Disallowed match patterns ('_', and '$n') as argument to
	      mnesia:delete_object/1 and friends.

Annoyingly it was actually us who reported this.

So your options are:
- use R12B-4 or earlier
- wait for RabbitMQ 1.5.0
- build the RabbitMQ server from the current default head in the hg 
repository

Apologies for the inconvenience.

Matthias.
