AFAIK, I did nothing to cause kwallet to be accessed, and I don't use kmail
either. OTOH, I did notice a whole bunch of duplicate processes while kded
was looping the CPU into overheat. I think they were kio_file or
kio-something-or-other, 6-8 of them.

A better place for others to find might be
http://bugs.kde.org/show_bug.cgi?id=168901 but I'll take it here. Will it
work without a complete kdm restart?
The ultimate solution is system replacement. I already built it weeks ago. I
just have to get an OS chosen and installed, the former of which has been
proving difficult due to my mandatory requirement for X to have functioning
panning virtual desktops, AFAICT missing from openSUSE 11.0 & 11.1 and other
xrandr distros released in the past year or more.
