I assume test-scp.odt is the good copy and test-gftp.odt is the corrupted copy. test-gftp.odt is (to be more specific) truncated rather than corrupted: as far as it goes, it's identical to test-scp.odt, implying a dropped connection or something of the sort.
Can you specify what FTP server is on the other end and what sort of connection is between the gftp client and the server?
