When downloading the Redhat Fedora Core 2 DVD ISO from the included URL, at some
point download manager begins showing a negative number for the KB downloaded.
I'm imagining that too small of a signed variable is used for this and it is
looping. The download continues normally without error, however. Also, when I
was experiencing this issue, the download speed was preceeded by negatives as well. 

Example: -178.-6 KB/sec; 

Reproducible: Didn't try
Steps to Reproduce:
1. Go to "ftp://mirrors.kernel.org/fedora/core/2/i386/iso/FC2-i386-DVD.iso" and
begin downloading.
2. Observe that at some point (I'm sorry, I wasn't watching continuously, so I
can't say precisely when) the "KB downloaded" reading becomes a negative number
counting up towards zero as the download progresses.
3. Also note the download speed being indicated in negative numbers.

Actual Results:  
Negative numbers displayed for "KB Downloaded" and "Download speed" fields.

Expected Results:  
The actual file size downloaded and the actual download speed should have been
displayed.

Sorry if this has already been reported. I couldn't find it.
