Under Active Window Control Settings, enabling the control buttons can cause segmentation faults when the mouse is hovered over the top left corner (where the buttons are) repeatedly. The faster the mouse is moved over the buttons the more likely it is that plasmashell will crash. plasmashell has to be started from the terminal after the crash.
If this is reproducible, please create a backtrace using the steps outlined at https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
