Comment 1 kde-bugs 2017-05-26 22:50:36 UTC 
When exiting Google Chrome, the screen is initially black, then the desktop is displayed without the taskbar panel being displayed.  After a delay, the taskbar displays.
Comment 2 kde-bugs 2017-05-30 05:13:41 UTC 
My initial comment wasn't clear.  The crash is when I exit Google Chrome.

My comment about having started it using a keyboard shortcut is how I started Chrome before the crash - the crash happening upon exiting Chrome.

New crash information added by DrKonqi

plasmashell (5.9.5) using Qt 5.7.1

- What I was doing when the application crashed:
     Closing Google Chrome via shift-ctrl-q  (This happens only if I open Chrome via a keyboard shortcut)

- Unusual behavior I noticed:
     Screen blacks out
     Desktop reappears after a few seconds
     After several more seconds, the taskbar reappears
