Application: plasmashell (5.18.5)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 4.12.14-lp151.28.48-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to move an icon on the desktop to a new location.  I have my desktop icons arrayed in two groups in the lower right- and left-hand quadrants on the desktop. I deleted an icon from the left-hand group and added a new app icon to the desktop. That icon was shown in the upper left-hand quadrant of the desktop. When I tried to move the icon to the lower left-hand grouping (quadrant), the desktop crashed. I deleted the new icon and tried again. Same result: desktop crashed. I tried this three times. Same result each time.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
