Operating System: Linux 4.17.1-1-default x86_64

-- Information about the crash:
- What I was doing when the application crashed:

I updated my OpenSuse tumbleweed with zypper dup on monday, 06/18/2018

Afterwards I get a crash on every login. Sometimes the loading screen after login (rotating wheel) freezes and I have to reboot.

-- Backtrace:
Application: KCMInit (kdeinit5), signal: Segmentation fault

I guess this is also the reason which prevent me to use GUI.

I "zypper dup"-ed my openSUSE Tumbleweed installation at Jun. 19.
Then after each restart, the mouse will always "remember" the first point I clicked.
E.g. If I clicked the KDE logo (*Windows' Start*) at very beginning, then wherever I move the mouse cursor to, my click will always trigger the start menu to be shown.

My temporary workaround:
- Switch to a text VT (Ctrl+Shift+F1)
- `pkill -U my-account`
- `kill` the pid of `kcminit mouse`
- restart sddm
