Application: plasmashell (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.3.0-28-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:

After I called Kickoff with Win key and then pressed Esc I got plasma crash report.

Kickoff didn't close and system tray moved to the left possible position (it was sticking to the right side).
So maybe kickoff is unrelated and the real troublemaker here is panel.

I have double monitor setup and global menu widget on both monitors (double panel) with tray widget on the primary.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
