When trying to recreate a PDF document from a large packet capture, the file
size is wrong and file is corrupted.

First noticed in Wireshark 0.99.8.  Works in 0.99.7 and below.  Hasn't worked
in any later release.

I have a large packet capture that was created for a class for hands on
practice exercises.  In this packet capture, there was a PDF document
transferred using FTP.  Recreating the TCP Stream for just the FTP-DATA, I get
848621 bytes for version 0.99.7 and 840077 bytes for version 0.99.8 and above.  

attached is the ftp-data packet capture.  If the file is recreated correctly,
it should be a pdf file titled IPSwitch WS_FTP Server User's guide but as
stated, this hasn't worked after version 0.99.7.
