Hi Francesco,

This indicates a problem that we should take a look at. In order to
duplicate the problem here, it would be very helpful if you can send us the
script along with any data files required to run it. If it is a complicated
scenario, it would be helpful if you can simplify it as long as it still
demonstrates the problem, but this is not required. The "Report Bugs" page
tells you how to send us the files. Be sure to let me know the names of any
files you upload to the ftp site, because we cannot see the contents of the
"incoming" directory.
