The package contains a D-Bus session service whose filename does not match the Name field found in the file. This makes it possible that two non-conflicting packages could provide the same service name with the same search-path priority (i.e. in the same directory). dbus-daemon will arbitrarily choose one of them, which is unlikely to be the desired result.
Best-practice is that if you implement a session service whose well-known name is com.example.MyService1, and it should be service-activatable, you should achieve that by packaging /usr/share/dbus-1/services/com.example.MyService1.service.
