Does anyone else suffer this ailment?

In KDE, my right ctrl key is sending ctrl AND THEN a linefeed. It is REALLY
annoying.

It's a PS/2 Dell keyboard and I use a Dell USB mouse. This doesn't happen at
the console.

bill$ xmodmap
xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Alt_R (0x6c),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L
(0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

My /etc/conf.d/keymaps just has
KEYMAP="us"
SET_WINDOWKEYS="yes"

and that's it. My keyboard layout is for a generic 104-key keyboard. I use a
USA layout and a Greece polytonic layout which yields this in the KDE
keyboard layout screen:

setxkbmap -model pc104 -layout us,gr -variant ,polytonic

Also, it doesn't repeat.

Wow, it gets even more weird. I just ran "startkde" from xinit and with
EVERY keystroke I see "kglobalaccel" spewing out EVERY

 "GlobalShortcutsRegistry::registerKey: Registering key "blah blah blah" for
"KDEappgoeshere" : "Shortcut name"

and then unregistering the whole set again. I can kill kglobalaccel and it
stops the printout, but I still get the weird linefeed when I use the right
control key in a terminal.
