Skydock thinks an image is untagged if the it has 2 names

[jderusse]

If you tag the same commit with 2 differents image's name, when you start the containers with image A, docker may register image B un the Config section. It's not a problem except for skydock who thinks that the image is not tagged and returne a ErrImageNotTagged error.

$ docker images | grep d3b7d9f39158
foo-mailcatcher                                       latest                d3b7d9f39158        5 days ago          381.3 MB
bar-mailcatcher                                      latest                d3b7d9f39158        5 days ago          381.3 MB

$ docker run -d --name foo foo-mailcatcher
b9c81f106ad0509edc15d34305bb26ba766a465462d4a3a0f20f0f75e239e069
$ docker run -d --name bar bar-mailcatcher
80a7fe67d59d92b88d2121a75ce3b4e3bb9c19105e2f167bfaa79ceb288ca78a

$ docker inspect --format '{{ .Config.Image }}' foo
bar-mailcatcher

$ docker inspect --format '{{ .Config.Image }}' bar
bar-mailcatcher

The first image will raise a ErrImageNotTagged in skydns

If I remove this lines https://github.com/crosbymichael/skydock/blob/master/docker/client.go#L111:L113 ,it's works fine.

What's the reason of this part of the client?
