Sessions crash. It's been a fact of life and it will remain so in the future. The fault can lie with any number of components inside and outside of KDE.

As of KDE 4.3, the state of a session, roughly, which applications and windows are open, is only saved (unless prevented by a preference setting) when the session is orderly closed. Obviously, a crash is the opposite of orderly.

After a crash, when the user starts a new session, what they get is not the last state they've seen in their previous, ill-fated session. Rather, the state of the last orderly terminated session is resurrected. For people who regularly put their computers to sleep instead of shutting them down, this state can be days, even weeks, old.

This behavior is at best counter-intuitive and at times rather annoying. At any rate, it destroys work the user has done and does it in such a devious way that it can't even be prevented by regular backups.

So, my plea is, to not only save session state when the session is closed, but rather do it periodically, say every few minutes.
