Stopping periodic xkbcomp reports

[Brad]

I'm running X Server 1.4.0.90 and every now and then - every
day or two - the following is logged in my xdm.log:

 The XKEYBOARD keymap compiler (xkbcomp) reports:
 > Warning:          Duplicate shape name ""
 >                   Using last definition
 > Warning:          Duplicate shape name ""
 >                   Using last definition
 ... and so on ...
 > Warning:          Multiple doodads named ""
 >                   Using first definition
 Errors from xkbcomp are not fatal to the X server

By switching /usr/bin/xkbcomp with a stub I've discerned that
the program is being called by the X server as follows:

 xkbcomp -w 1 -R/etc/X11/xkb -xkm - -em1 \
"The XKEYBOARD keymap compiler (xkbcomp) reports:" \
-emp ">"  -eml "Errors from xkbcomp are not fatal to the X server"
/var/lib/xkb/server-0.xkm

My X server is otherwise running perfectly, as far as I can tell.  I have
these xkb options in my xorg.conf file:

Section "InputDevice"
   Option  "XkbRules"  "xorg"
   Option  "XkbModel"  "pc104"
   Option  "XkbLayout" "us"
   Identifier     "Keyboard1"
   Driver         "kbd"
EndSection

There aren't any errors reported in Xorg.0.log:

...
(**) Option "XkbRules" "xorg"
(**) Keyboard1: XkbRules: "xorg"
(**) Option "XkbModel" "pc104"
(**) Keyboard1: XkbModel: "pc104"
(**) Option "XkbLayout" "us"
(**) Keyboard1: XkbLayout: "us"
...

It's a bit irritating with this xkbcomp report being produced every day or
so.  Could someone point me to where I can find out what I've presumably
missed in setting up my xorg.conf, or otherwise how to turn it off?

Thanks,


Brad
