Dear all,

After upgrading org to 9.3.6-25  (Org mode version 9.3.6
(9.3.6-25-g685b2c-elpa @ /home/tomas/.emacs.d/elpa/org-20200316/)  I get
the following error when trying to evaluate gnuplot source blocks:

easy-menu-convert-item-1: Invalid menu item in easymenu

I use gnuplot snippets a lot in my org-mode files, and I am clueless as how
to fix this.  Any fix / pointer / suggestion will be very appreciated.

Thank you

Tomas
