Yeah, KDE shouldn't have done that. This has been reported before. It's even documented in the wiki page that we take the liberty to change the formatting of that string any time: http://www.freedesktop.org/wiki/Software/systemd/dbus/ It is totally non-sensical to check for software versions the way KDE does it. We supply them with a call to check whether a certain operation is available (CanSuspend(), CanHibernate(), ...). They should just call that. It will tell them precisely whether the operation is not implemented in the code, or whether it is available on the hardware, and so on. But no, they decided to involve version checks...
