UnboundLocalError: local variable 'region_name' referenced before assignment

[Parveen Sharma <parveenks.ofc@xxxxxxxxx>]

Hi,

I'm getting "UnboundLocalError: local variable 'region_name' referenced before assignment"  error while placing an object in my earlier created bucket using my RADOSGW with boto.

My package details:

$ sudo rpm -qa | grep rados
librados2-10.2.1-0.el7.x86_64
libradosstriper1-10.2.1-0.el7.x86_64
python-rados-10.2.1-0.el7.x86_64
ceph-radosgw-10.2.1-0.el7.x86_64
$

$ python 
Python 2.7.10 (default, Oct 23 2015, 19:19:21)

https://bugzilla.redhat.com/show_bug.cgi?id=1343813  is mentioning a workaround but it apparently not working for me or I am missing something.
