Did the compositor crash maybe? This isn't really a crash but qapplication failing to start.
Yes the session was destroyed. The starting bug/crash was applying settings in systemsettings: https://bugs.kde.org/show_bug.cgi?id=483072

I don't have a clear way to reproduce but each time I see this crash, it happens when restoring an application using the tray icon if the screens were turned off due to inactivity before (not immediately before, but I don't think I ever had the crash if the screens didn't turn off before) coredumpctl always saves bt for gmenudbusmenuproxy, kwalletd6 and kwin_x11 in this case (and sometimes xembedsniproxy)
