Unable to kill/restart/stop containers with 0.9.1 and Ubuntu 14.04

[javacruft]

I can create and run containers just fine; however if I try to stop/restart/kill them I get the following error in the docker log:

[debug] server.go:924 Calling POST /containers/{name:.*}/kill
2014/04/08 15:35:28 POST /v1.10/containers/198df4757679/kill?signal=KILL

Downgrading to a 0.8.x release allows me to perform these actions

This looks to me like it's the apparmor issues that were fixed in master by #5049 - any chance you could test out that change and let us know? :)

Testing that patch now

@tianon that fixed things up nicely although I did have to remove the existing docker apparmor profile to make docker generate a new one.
