Description of problem:

When the DeploymentConfig has multi-container pods, the image is not updated after the build is finished. 

Version-Release number of selected component (if applicable):
$ oc version
oc v3.3.0.30
kubernetes v1.3.0+52492b4
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://master.manage.bm.chmouel.com:8443
openshift v3.3.0.30
kubernetes v1.3.0+52492b4

How reproducible:
everytime

Steps to Reproduce:
oc new-project test-multicontainer
oc new-app
centos/ruby-22-centos7~https://github.com/openshift/ruby-ex.git -o yaml
> 1.yaml

vim 1.yaml

# add a new container to the pod :

       containers:
        - image: ruby-ex:latest
          name: ruby-ex
          ports:
          - containerPort: 8080
            protocol: TCP
          resources: {}
        - image: ruby-ex:latest
          name: ruby-ex2
          ports:
          - containerPort: 8081
            protocol: TCP
          resources: {}

# and also add ruby-ex2 to  containerNames:

    triggers:
    - type: ConfigChange
    - imageChangeParams:
        automatic: true
        containerNames:
        - ruby-ex
        - ruby-ex2

oc create -f 1.yaml

The deployment fails :

$ oc get pods
NAME               READY     STATUS      RESTARTS   AGE
ruby-ex-1-build    0/1       Completed   0          15m
ruby-ex-1-deploy   0/1       Error       0          13m


Actual results:
whole dc after build is finished: https://gist.github.com/fridim/aa3491eac28ee0ad7c4fd3b87da10641

Expected results:
both image for containers should be updated with something like :
        - image:
172.30.87.209:5000/test-multicontainer/ruby-ex@sha256:9fb754049d4f97df32572baccddcbfa34fecbcc559efa7bf16441e4437acb25a


Additional info:
WORKAROUND:
 Create one triggers[].imageChangeParams  by container with only one
name in containerNames[]  then it's OK
example: this one works:

DC shows image updated for both containers:
