RemoteUpdateManager does not exit (no return code)

The updates are installed properly and the log says "all updates were installed" or "everything is up to date" but the remotemanager doesnt stop (i.e. it doesnt return an exit code).

This comportement happens without the involvment of a in-house update serveur.

If I use an older package (one that was made with the cloud packager 1.5 -  I have since updated to the 1.7 version), I dont get this.
