It seems this sometimes might occur if the containers package cache is out of date. I use the "--no-download" option to try to force apt-get to only use the upstart-sysv package retrieved by dget. However, according to man apt-get, it's best to also use "--ignore-missing" to truly force apt to only use the downloaded packages.
I'll add that option as well and hopefully it will fix this.
