KDE with fam is broken, according to=20
http://wiki.freebsd.org/KDE4
A work-around is to change the PollInterval in kdedrc
baby-jane:~$ less .kde4/share/config/kdedrc
[$Version]
update_info=3Dkded.upd:kde3.0
[DirWatch]
PollInterval=3D60000
(IMHO, for KDE issues you should ask on the kde-freebsd@kde.org mailing
list).
