Comment:

 I've just come across this bug myself, too.  Attached is a patch I came up
 with (before seeing this ticket) to fix it.  It takes a slightly different
 approach to the above - rather than checking for a zero value, it
 subtracts 1 before the % operation, then adds it again; this is almost
 equivalent, but if the actual tierImageSize value was 0 it would leave it
 at zero.
