[Bug 1759328] [NEW] computer crash when I change the desktop configuration

[trotosa]

Public bug reported:

On Kubuntu 18.04 beta 1 release

A right clic on the desktop give me the access to the desktop
configuration.

I have 2 choices for the desktop view : "desktop" or "directory view".
When I change the last choice selected and apply the modification, the computer crash.

I can't do anything else and must use the power button to restart the
computer.

After reboot, the desktop configuration is changed.

PS : when the selected choice is "directory view", vertical scrolling
has no effect for changing from virtual desktop to an other one.

Please, be helpfull, english is not my native langage and may be the package is not the correct one.
informations are :
KDE frameworks 5.44.0
Qt 5.9.4
.xcb
