I toyed around a bit based on the post #11 from Alkis Georgopoulos
(thank you for that, vala-panel-appmenu.sh is indeed the culprit, that was really really helpful)
One solution is change the exec line in the desktop file like: env GTK_MODULES=glade glade %f
this is one solution that works.
But I think a better solution would be to delete /etc/profile.d/vala-panel-appmenu.sh altogether because the environment variables GTK_MODULES and UBUNTU_MENUPROXY are both not in use in Ubuntu-MATE and AFAICT for GNOME-Desktop only.
I deleted /etc/profile.d/vala-panel-appmenu.sh
It works without problem and I think it is a bit more elegant.
Could/should the file /etc/profile.d/vala-panel-appmenu.sh be marked as a conflict against mate-desktop-environment package ?
In that case it would only be installed if the desktop is NOT Ubuntu-MATE
