[rabbitmq-discuss] cannot redeclare exchange with different type

g'day folks,

just been rummaging through the rabbit mq tutorials and got myself stuck in 
a slight rut.

i'm perusing the pub/sub example in python on windows. 
i've declared an exchange, and having run the script, I can see it's been 
created through the management console,
but I keep getting an exception as soon as I run either the producer or the 
consumer app.

if I comment out the exchange_declare line, all is well.

the logger says I cannot redeclare an exchange with a different type.
in the management window I can see it is of type fanout. the code is 
declaring it as fanout.
I was under the impression exchange_declare was idempotent. is this correct?
