I guess there was an incoming D-Bus request when deb-systemd-invoke stop tried to stop the service in prerm, so this request was cancelled. For socket activated services, we can stop the .socket unit in such a case [0] to avoid being started by an incoming request. For D-Bus activated services there is no such equivalent. So I don't see a good way to fix this. We'd need some kind of manual state a service can be put in during package installation/upgrade/removal time, i.e. it would need support from systemd. I'm not sure if blacklisting the service in prerm would help here. I vaguely remember discussing that a while ago and blacklisting had some unwanted side-effects. This might be a good topic for the sprint this weekend, I think, since we have quite a few D-Bus activated services.
