I upgraded from Scott's ppa and still see the signs of bug 855030:

AMQPChannelException: (404, u"NOT_FOUND - no exchange '4b0a4421eb4a44ce96ce5f71c8523d16' in vhost '/'", (60, 40), 'Channel.basic_publish')

I looked at /usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/session.py and verified that it had the change mentioned in Scott's last comment. Many vms are created successfully but eventually this always happens to me when I create multiple instances with a single euca-run-instances command. I cannot understand why others do not see this problem. I will reopen that bug.
