It may be that KDE is doing "but I want to access $HOME _all_ the
time" and the fileserver then mobbing out that client after trying
many times without permission.

That's so last century, but that should not have an impact on the
problem.

For your problem, it might be good to upgrade to at least 1.4.7, but because of
the security problem I'd upgrade the client all the way to 1.4.10.

Doing a cd where makes things work again?

$ fs la ltu.se/staff/s   
fs: You don't have the required access rights on 'ltu.se/staff/s'

Seems you don't have system:anyuser list. It would probably make
your life easier if you had that down to $HOME and then give
your users a $HOME/Private/ and a $HOME/Public/.
