[Patrick Hetu]

root@os:~# dpkg -l | grep glance
ii glance 2011.3-0ubuntu4 OpenStack Image Registry and Delivery Service - Daemons
ii python-glance 2011.3-0ubuntu4 OpenStack Image Registry and Delivery Service - Python library

/usr/lib/python2.7/dist-packages/glance/common/exception.py use _() for translation but the function is not imported.
So when horizon try to call it, failed.

    load gettext in __init__ to fix '_ is not defined'

    gettext.install needs to be run on every potential entrypoint; this
    resolves bug #885529 (the python standard library includes a noop
    gettext library for this purpose). This is also how nova does it.
