In a way, you could say that it's the FTP server's fault, but
only if you have very good reasons to support that IE's ftp
client mode is perfectly fine (which it isn't, but this is my
personal opinion, of course).

Because the parsing of FTP server's output for "dir" commands,
that show the listing of files in a directory, is implemented
entirely on the client side, and in this case it's horribly
broken.

No.  I've wasted many hours trying to access FTP sites that don't
run FreeBSD too, when I was forced to use IE as my "interface".

    1. IE's ftp-client asks for a directory listing.

    2. The ftp server provides one.

    3. IE's ftp-client side tries to parse the listing.

    4. It fails.

As you said... it's an IE problem :)
