I did a patch for this BUG - and for me, it seems to run. Sorry, but I had
to introduce a new ErrorCode - that is only used internally. I can also
define a flag in one of the structures to transport the needed information
between the calls.

I tried not to change to much. Would you please have a look on the changed
files (diff against 7.16.0 is attached) if you see any problems. I am open
for all comments.

Thanks!
