Thanks Hans for this quick solution. I like the new approach, no
fiddling with test backgrounds.

However, the old mechanism did not draw the rule through where the
graphics are inserted. I don't know why, but that was exactly what I
needed. The new mechanism draws a rule regardless of the presence of
a graphic. See the attached examples.

With the dummy pictures it looks quite okay with the line drawn
through. But in the document several graphics already have a frame,
which then visually interferes with the column separator rule.

Is there a way to get the old behaviour?
