Deployment with no action groups

Using v4.3.6 if you try to deploy to an environment which has no action groups, buildmaster tries to start the job but does nothing (as there is nothing to do) but the job never finishes and cannot be cancelled.

A minor issue, in this case we had forgotten to copy the action groups to this environment, but previously the deployment would have completed almost immediately, where as not it hangs.

Product: BuildMaster
Version: 4.3.6

Thanks; we were able to reproduce this, and will revert it to old (correct) behavior in a maintenance release.
