When downloading a file, the progress bar "progresses" like this:

 % Total % Received % Xferd Average Speed Time
Curr.
                                 Dload Upload Total Current Left

(I've pressed return at strategic moments to make the output visible.)

Notice the third line. Average dload speed has been set to 1 byte/sec even
though no bytes are actually downloaded, which means the estimated time
explodes and does not fit in its allocated space, thus leaving a "0" at the
end of the line for the remainder of the download.

I've patched this so the '=1' assignment doesn't occur. I couldn't see why
it's done in the first place. (Daniel, please enlighten me! :) Anyway, now
it looks nicer:
