The problem that you encountered has been fixed in our upcoming release (a
day or two). We will be updating the CVS repository at that time.  Thank you
for pointing that out to us.  It slipped through our test net. However, we
have done a complete re-write of the clone and import sections, so the fix
is not usable, but very much appriciated.
