    <thetext>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&apos;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 &quot;/lib/x86_64-linux-gnu/libthread_db.so.1&quot;.
