For future reference (and thanks to Peter Flynn of the Latex user group),
using absolute instead of relative font sizes plus the selectfont command
solves the problem:
\addtokomafont{caption}{fontsize{8}{10}\selectfont}
It smacks a bit of finger painting, but works well.

I thought I would ask a Komascript question, as there seems to be several
expert users on this forum.
I'd like to have captions in table and figures in a smaller font size *and*
with a correspondingly smaller leading space.
I know I can change the font size with
\addtokomafont{caption}{\smaller}
