Whatever is using "df" to determine the amount of free space on AFS
will utterly fail.

I would suggest to file a bug with KDE development.

Not that KDE is the only place where such things happen.

AFS, sshfs, and possibly others are utterly useless targets for "df".

Attempting to manually (essentially) analyse file permissions based on
UNIX permissions, available disk space based on df, etc. are concepts
that are doomed to fail.  I don't think it should be done at all because
there are edge cases (such as using AFS) where the conventional UNIX
semantics just don't apply, but you can still do whatever it is that
you intended to do.  Applications that try to be smarter than you and
the OS combined are poorly behaved, I'd say.
