[with overused fixer] I've seen similar results on the print
edges after KRST toning.

This seems to happen if the fixer has a lot of dissolved
silver in it.

Taking a print directly from the fix to KRST only works
if the fix is squeaky new.  The best bet is to use two
(or three - the third only needed for KRST) fixer baths.

FWIW: putting unprocessed paper in KRST does turn the
KRST dark and cloudy - starts out light brown and ends up
purple-grey.  A black precipitate is formed and the
paper goes a dark tan.

So it seems this will happen if the fix isn't fix or
is completely spent.
