Comment 1 for bug 1361134

At present, I change the /usr/lib/python2.7/site-packages/glanceclient/openstack/common/strutils.py safe_encode function
and avoid this issue.
e.g:
def safe_encode(text, incoming=None,
                encoding='utf-8', errors='strict'):
=>
def safe_encode(text, incoming=None,
                encoding='utf-8', errors='ignore'):

"errors" from 'strict' to 'ignore'
