Description of problem:
Attempting to remove an image, an error message is reported stating that a container is using the image. All containers are stopped:

$ docker rmi fbe51255ac15                 
Error: Conflict, cannot delete fbe51255ac15 because the container a0a8d8de4744 is using it, use -f to force
$ docker rm a0a8d8de4744 
a0a8d8de4744

After removing each container the error message reports, the image still cannot be removed, reporting the following error stating the image id cannot be found:

$ docker rmi fbe51255ac15
Error: No such id: b8c287cf50a1151c53d1b7e6102661b01a54e61c52cd491a70476d242e92ac57

However, the image is still seen in the `docker images` output:

$ docker images | grep fbe51255ac15
<none>                            <none>              fbe51255ac15        2 days ago          469.3 MB

It is difficult to reproduce the issue consistently. The issue has been reported on the dotcloud github issue tracker. It appears this may have already been resolved upstream:
