Re: ange-ftp errors out for some directories

[Richard Stallman]

    I finally got round to debugging this properly, it turned out
    that both dired-actual-switches and the dired buffer were being
    reset in ange-ftp-insert-directory.  Specifically,
    file-symlink-p seemed to do the resetting.

It is certainly a bug if file-symlink-p does that.  Can you find out
where within file-symlink-p that resetting happens?

I would guess it occurs inside of ange-ftp-file-symlink-p, which I
would guess is handling the operation in this case, so you could first
try debugging inside there.
