Okay. The quick fix is to remove the extra Glance V2 call when CONF.allowed_direct_url_schemes is disabled.
This effectively avoids calling the Glance V2 API on python 2.6 (thus avoiding the schema validation issue).
The real issue here is still unresolved however and it looks like we still have some work to do to get all the fancy new Glance V2 stuff fully working on python 2.6 distros (RHEL/Centos, etc).
