Resizing the Fabric ensemble fails with io.fabric8.api.InvalidComponentException

Issue

We try to enlarge our Fabric ensemble using fabric:ensemble-list but some of the containers added to the ensemble fail to reach a provision status of success. Instead their status is error - io.fabric8.api.InvalidComponentException as in this example:

[id]        [version]  [type]  [connected]  [profiles]              [provision status]     
fabric-001  1.0        karaf   yes          default                 success                
                                            fabric-ensemble-0001-2                         
fabric-002  1.0        karaf   yes          default                 success                
                                            fabric-ensemble-0001-3                         
fabric-003  1.0        karaf   yes          default                 error - io.fabric8.api.InvalidComponentException                
                                            fabric-ensemble-0001-4                         
fabric-004  1.0        karaf   no           default                 error - io.fabric8.api.InvalidComponentException                
                                            fabric-ensemble-0001-5                         
root*       1.0        karaf   yes          fabric                  success                
                                            fabric-ensemble-0001-1                         

The problem is not reproducible at will.
