Description of problem:

When an object (exchange/queue/binding) is created using qpid-config or addressing, second try to create the same object do not output any error, return code is 0

When an object is created using QMFv2, second try to create the same object outputs following error:
Error: error_code=7 error_text=object already exists: <object-name> 

All the methods shall have the same behaviour.

This was seen on RHEL5.6 x86_64

How reproducible:
100%

Steps to Reproduce:
Please, see additional info
  
Actual results:
Different behaviour while creating broker objects dependent on method used (qpid-tools, addressing and QMF).

Expected results:
Same behaviour for all the methods used for broker objects operations
