Here's my guess at the cause.

Occasionally, you might notice in a Finder list view window that a file is
listed as smaller than it really is.  This often happens when downloading a
file with a terminal emulator.  (I guess the Finder notices the new file and
remembers its initial size and doesn't update it.)  You can get the Finder
to update the size by selecting the file and choosing Get Info.

I think that if you try to copy a file like this, then you get the stange
behavior in the status dialog.  I guess that the Finder computes the mapping
between bytes copied and percent done based on what it thinks the size is,
and things go wrong when the file ends up being larger than it expected.

When I first saw this I thought it was kind of amusing, and I didn't realize
what caused this until someone explained this theory.
