It's the spec of the default face, so its realization takes place before 
the realization of the other one (DejaVu Sans), and the medium weight is 
selected.  When Emacs tries to realize the DejaVu Sans font, it sees that 
DejaVu Sans does not have a medium weight, and it is rejected.

Okay, I'll try to find out if I have time.

If bug fixes did not create other bugs, programming wouldn't be fun, isn't 
it? ;-)
