PROBLEM SOLVED: This is again something weird! None of the methods
setting that nasty switch including dconf-editor, gconf-editor,
dconf set org.mate... worked, although all methods pretend that
that switch had been indeed set correctly.

Instead, only one specific command sets the right switch at the
correct place:

dconf write /org/mate/desktop/background/show-desktop-icons true

Specifically note that again, the 'desktop/' part is in that
path. So I suspect that this change in name and the special path
entry in the schema confuse mate in such a way that the config editors
do not find the switch at the correct place, only 'dconf write'
hits the right bits.
