User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

The download manager reports a negative amount for the file size downloaded and
consequently a negative speed.  The file size being downloaded is 2.7GB.  The
problem surfaced around 2GB mark of the download.  This is most likely due to
the fact that a 32bit integer is used to store the amount downloaded (2^32 =
4294967296, and with a signed int you have half or 2147483648 or 2GB for
positive sizes).

Reproducible: Always

Steps to Reproduce:
1. Download a file that is >2GB
2. Wait til the downloaded size is >2GB
3. See the negative downloaded size and speed

Actual Results:  
I view the incorrect speed and downloaed amount (the negative numbers).

Expected Results:  
It should report the correct downloaded size and speed (a positive number).

I have a screenshot showing what happend, and can send it if needed.
