Title:
glanceclient/common/utils.py safe_header throws an exception on X
-Auth-Token with None value
Status in python-glanceclient:
Fix Committed
Bug description:
When using the glance-client with an internally generated admin
context (e.g. using nova_context.get_admin_context) the
log_curl_request fails due to safe_header trying to
"value.encode('utf-8')" on a value that is None.
An example of a stack trace (coming from RH juno distro's
nova.compute.manager but the potential problem exists in Kilo &
Liberty):
