Thanks to all for your answers! Abe, "pigment_pattern{wrinkles}" works just
fine. I really didn't think of converting a pattern initially created for
normal (ditto POV-Ray manual, 3.5.11.37) into a pigment pattern to use it
in a normal. And even better: i think your workaround makes a better rough
wall finish than directly applying a "wrinkles" normal pattern.

I can now go on with my scene, but I guess that leaves the following issue
open: "is it a bug or a feature?" ;-)

J-Y
