[Bro] FTP Filenames used for file size in some cases?

It looks like Bro is logging part of the file name as the file size in some
cases.

I'm using Bro 2.3.2 on Cent 6.6 x64, libpcap 1.4.0.

What I'm seeing is that we have some regular FTP activity that looks like
this:

command
arg
file_size
RETR ftp://{ip}/DIR/SUBDIR\ARCHIVE/9254493514002F.TIF      9254493514002
RETR ftp://{ip}/DIR/SUBDIR\ARCHIVE/9254493514006R.TIF      9254493514006
RETR ftp://{ip}/DIR/SUBDIR\ARCHIVE/9254493514043F.TIF      9254493514043

My google fu might be off, but II'm going to be rolling out 2.4 but I can't
do it right away.
