Open Stack

Installed Devstack, created a volume, a snapshot and launched an instance
based on the snapshot. When I try to access the instance details in
Horizon, it blows up with this exception. Looks like some component can’t
handle cinder v2, where the display_name attribute has been replaced by
name.  I found older bugs describing this issue, but they are marked as
fixed. Is this a known issue? Would appreciate help with a workaround.
