Created attachment 101941 [details]
New crash information added by DrKonqi

kwin_x11 (5.7.5) using Qt 5.6.1

- What I was doing when the application crashed:

Applications (kconsole or conversation window after  KDE Telepathy) 
run with the emergency shift of application windows up 
(so that the application window disappears title)

This effect appears only when you start the first application.
