kde does not restore session

Hi all,
I have configured my kde to restore previous sessions but I have noticed that once I restart my system or my system crashes I never get back the session as it was (relaunching chrome browser, the kwrite windows and my beloved konsole).

It is only two weeks that I install the leap 42.2 so I do not consider that I have really touched a lot my distribution to the level of causing this behavior.

Any ideas will help.
Regards
Alex

What’s more interesting is why your system crashes. It shouldn’t. Did you add any repos ? Please post output from

zypper lr -d

Yes, your system should not crash.

But when it crashes, how would you think that KDE can store information on what to restore on a new login?
When you logout, KDE stores what it is running, etc., but when it crashes …
