You use the phrase "expanded to garbage"... I have experienced file
corruption in the past using Netscape on Linux when the server
was saying the file MIME type was text.  The symptoms were that the
file would not expand at all, though, so this may not apply in your case.

The correct answer was for the server administrator to fix the MIME
type reporting, but sometimes they are too clueless to respond to
the cluebat, and my workaround at that time was to use IE to download
the files on Windows, and I haven't experienced it in awhile so either
the cluebats have been working or Firefox is implementing the M$-approved
second-guessing of file types.
