Additional info:
This looks to be the same as the issue in BZ 1104239 however, these are more recent packages than the ones reference in the errata.

Comment 2 Artom Lifshitz 2016-03-31 17:08:39 UTC

Hi,

I haven't been able to reproduce this with the latest python-migrate-0.9.6-1.el7ost package in RHOS5.

Based on the information in BZ 1104239, I diff'ed the different versions's migrate/changeset/__init__.py files and sure enough, the guilty line is present in 0.9.1 but absent in 0.9.6:

$ diff 0.9.1/usr/lib/python2.7/site-packages/migrate/changeset/__init__.py 0.9.6/usr/lib/python2.7/site-packages/migrate/changeset/__init__.py
8d7
< import warnings
12,13d10
< 
< warnings.simplefilter('always', DeprecationWarning)

Cheers!

I verified the fix is in the puddle and our automation didn't report any issue.

according to the DEV report I am moving this ticket to verify
