I was downloading the Fedora Core 3 Test 2 iso from:

ftp://ftp.ndlug.nd.edu/pub/fedora/linux/core/test/2.91/i386/iso/FC3-test2-i386-DVD.iso

And after awhile, I came back and saw the download manager was showing negative
numbers. Here is an example of the output below the download progress bar.

-411000KB at -40.-9 KB/sec; unknown file size

The file was really at around 3.7GB downloaded out of 4.2GB. And the transfer
rate was something around 300KB/s. At the beginning of the download, the size
was unknown, the size downloaded was incrementing from 0 correctly, and the
transfer rate was 300 KB/s+. Nothing out of the ordinary. After awhile, it
started showing the wrong output above.

The first number, was decrementing to 0 from a high negative number. And notice
there is a negative number to the left and right of the decimal in the transfer
rate. I think this



Reproducible: Always
Steps to Reproduce:
1. Download the ISO at the URL given above.
2. Wait awhile as the file downloads.


Actual Results:  
Eventually the progress output statistics will show incorrect readings.

Expected Results:  
The output should have been something like:

3,768,022KB at 321.00 KB/sec; unknown file size

Similar problems were reported before bug 231361 was fixed. Strange...

Fedora is still downloading. Just to add to the original posters comment a
screengrab of the download window to visualise things can be found here:

Here is the picture given by the poster above. My example given looks just like
this.

Attachment: Download manager shows negative percentage of a downloading file of unknown size.

Downloading 3 Mandrakelinux 10.0 Community ISOs and RealPLayer 10 and window
caption maintains "-1% of 4 files" although file transfers continue.
