See bugsnag.

For example, the workflow.py test file doesn't specify a docker like UA. Apparently, we have some other scripts as well around here (or maybe people are experimenting).

The reason it crashes is: https://github.com/dotcloud/docker-registry/blob/master/docker_registry/toolkit.py#L28

Questions:

• should we accept UA that don't contain docker/XXX ?
• if yes, then what would be the proper behavior? assume the latest docker version?

Need advice on this: @shin- @samalba
