I can't see how a "misc-fixed" default fault would prevent the use of
DejaVu Sans font for particular parts of the text.  This has worked for
the last 10 years or so, AFAIK.

I can't see which such attribute in my example would explain the
behavior I see.

I sense a bit of defensiveness in your responses.  I'm really trying to
fix an actual misbehavior in my config (one which at first sight looks
to me like a plain bug, or at least a plain regression).

What should I change in my recipe in order to keep the same default font
but get the DejaVu Sans that used to get?
