During logout, Plasma 5 restarts, an information about crash appears Reproducible: Always Steps to Reproduce: 1. Install openSUSE Leap 42.2 beta1 with default KDE desktop 2. Login into KDE Plasma session 3. Logout Actual Results: Icon about crash appears in system tray. I can press that icon, then crash reporter opens. Expected Results: Clean logout without reporting any errors As I can not stop logout, it is difficult to obtain information. How to revoke/cancel logging out process?

You can simulate the logout with "kquitapp5 plasmashell" from krunner (and "plasmashell" to restart it afterwards). We have one open crash for logouts, so if you can't get the backtrace, there's a good chance it's the same thing.
"kquitapp5 plasmashell" helped. Because of bug in KDE crash reported, button "Suggest this crash is related" and subsequent dialog is don't allow to continue to report. Thus I just copy-paste some crash info. Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
