Description:    Ubuntu 10.10
Release:        10.10

I've only noticed this after "upgrading" to KDE 4.6.2. With 4.6.1 it
never happened.

After a day or so of uptime I start to notice increasing amounts of hard
disc activity. This can occur at any time - when the computer is idle,
when I'm in the middle of sending an email, whatever. There appears to
be no pattern to it. The cause is the process kio_thumbnail - which is
thrashing the hard disc like crazy, using 100% of the CPU, and gradually
eating RAM (the last time I saw it it was using 2 Gigs of RAM, and
climbing).

There appears to be no way to kill this process - killall kio_thumbnail
has no effect, and killing it via the pid either crashes KDE, or KDE
just starts it up again.

Usually it will calm down for a while, only to start up again some time
later. Each time it gets worse and worse until eventually there is no
course of action left but to reboot. I don't have any open windows which
would require thumbnails to be created, so I've no idea what KDE thinks
it's doing.
