Description of problem:

When trying to create an exchange of different type with the same name as already existing exchange, no error message is displayed and return code is equal to 0 using the python client.

Following error is displayed using other clients (see additional info):
Create failed for exchange ex; not-allowed: not-allowed: Exchange declared to be of type topic, requested fanout (qpid/broker/SessionAdapter.cpp:125)

All the clients behaves the same way.

This was seen on RHEL6.1 x86_64, MRG 2.0 installed (this issue is also valid for MRG 1.3 branch)

Version-Release number of selected component (if applicable):
python-qpid-0.10-1.el6.noarch

How reproducible:
100%

Steps to Reproduce:
1. spout "ex;{create: always,node:{type: topic,x-declare:{type:topic}}}" 
2. spout "ex;{create: always,node:{type: topic,x-declare:{type:fanout}}}" 
3. echo $?
  
Actual results:
No error message displayed, return value is equal to 0

Expected results:
Error message is displayed, return value is non-zero

# qpid-config add exchange fanout ex
