KDE Crashes on logout and shutdown

[Guest]

KDE Crashes every time I logout and shutdown my computer. I have Yet another window control setting and yakuake installed.

Steps to Reproduce:
1. Logout / shutdown my computer
2. KDE Crashes
3. As a result logout and shutdown take longer than usual

Here's the crash log:

Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation faultUsing host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

How should I solve it ?

If you open a console window and run sudo poweroff, what happens?

If I logout / shutdown / restart from terminal that crash doesn't show up, it only shows up if I do that from the desktop
