Ok, this was just plain wrong.
This is a bug.
This kind of bug may seems odd but our 1516 implementation is
relatively new compared
to 1.3 so such stupid thing like this may happen due to the lack of time
for thorough testing... :-(
I did try a blind fix and committed it to CVS HEAD,
so please update your CVS tree and retry.

I won't have much time now to investigate the "time issue" now
but I would kindly take time to review patch proposal in this area.

I would be glad to ear about your pitch to CERTI porting experience.
may you can send us your master thesis when it is written.
