Description of problem:

When my browser language setting is Japanese, 'Delete Image' Horizon operation failed, but the image was deleted actually.
When my browser language setting is English, 'Delete Image' Horizon operation succeeded.
Image create/delete via glance/openstack client work without problems.

I am able to fix issue after applying https://review.openstack.org/#/c/227143/

i.e. 


- I updated: /usr/lib/python2.7/site-packages/horizon/tables/actions.py

806                 LOG.info(u'Permission denied to %s: "%s"' %   <==

[...]
816                 LOG.info(u'%s: "%s"' % <==
817                          (self._get_action_name(past=True), datum_display))
