I believe the easiest way to find out would be to compare the results of
your file against one created by our tools; problems like these might be
related to f.e. different char enconding ...

You dont have to bundle ca-files but can always let the user create
fresh ones self with the scripts we provide for this; but nevertheless
I'm interested into your code, and probably I can narrow doen the issue
you see, so are you willing to share it with us? Either send it to me
directly, or attach it here as file if you want to let others play wih
it too.

thanks, Gün.
