I don't know exactly what (inheriting from) default means with respect
to faces.  But in any case, a specific font doesn't have color
attributes, yet the default foreground (on a light background) is
black, and as you observed in another post, explicitly setting the
foreground to black shows the problem.  I'm convinced this is a bug,
though I have no idea just what causes it.

The left display margin (by default to the left of the left fringe) is
where you see the line numbers in linum-mode (starting with version
0.9a).  For info type `C-h i RET m elisp m Display Property' and from
there `m Display Margins'.
