Description Ivan Ivanov 2020-04-18 10:20:35 UTC

Operating System: Linux 5.3.0-46-generic x86_64
Windowing system: X11

-- Information about the crash:
1) create a new menu by right click on a planel -> add panel -> application menu panel
2) place he panel on another edge
3) the menu shows correctly, but trying to open any of the items cases Plasma to crash

I need that so I can have my menus on my multiscren setup. Currently running 19.10 with backports.

If you need any additional details, I will try to provide them.

The crash can be reproduced every time.
