Yes, sorry, it seems that custom-invalid got loaded when I ran customize-face to work out the test case.

`linum' is a face that inherits from default, so that's where I expected this came from.

Anyway, thanks for fixing this so quickly.

Is there another way to set the color of the background now?  We have the margin, then the fringe and then the regular window contents.  Normally, I would use the same background for fringe and margin.  

The `linum' face I mentioned just customizes actual line numbers, but not areas where there are no line numbers (e.g., wrapped lines, or beyond the end of the buffer, as in this example).

Pretty much everything else is customizable, so it would having a margin face would just be consistent.
