There's something more going on, I think.

I'm setting variable-pitch to use a family of "DejaVu Serif":

Face: variable-pitch (sample) (customize this face)
Documentation: The basic variable-pitch face.
Defined in `faces.el'.

        Family: DejaVu Serif
       Foundry: unspecified
         Width: unspecified
        Height: unspecified
        Weight: unspecified
         Slant: unspecified
    Foreground: unspecified
    Background: unspecified
     Underline: unspecified
      Overline: unspecified
Strike-through: unspecified
           Box: unspecified
       Inverse: unspecified
       Stipple: unspecified
          Font: unspecified
       Fontset: unspecified
       Inherit: unspecified

and I *have* a DejaVu Serif face:

but still, when I insert (propertize " " 'face 'variable-pitch), I get

It still fails, as shown above.
