Description:
Since around January 22, 2021, when I open a Libreoffice application (i.e. Calc or Writer) the Xfce4 indicator plugin crashes.
The system generates an error asking if you want to restart the plugin, but the action is not successful.
Any attempt to reinsert the plugin in the system tray while the Libreoffice application is still open, fails.
By closing the application, you can reinsert the plugin as usual.

O.S.: Xubuntu 20.10

2. Open a Libreoffice app (Calc or Writer)

Actual Results:
