Title:
flags.FLAGS( crashes bpython
Status in OpenStack Compute (Nova):
Fix Released
Status in openstack-common:
Fix Released
Bug description:
Bpython tries to do some fancy stuff like lookup obj.__name__ and
check for AttributeError. The code in common/cfg.py has a special
getattr that raises a non AttributeError exception so it leads to a
crash and stack trace in bpython:
Traceback (most recent call last):
