During an automated install/deinstall check the following error has happened:

ERROR: Output running pre uninstall script for package
gnome-bluetooth-0:0.8.0-2.fc7.i386
gconfd-2: no process killed

Changing the pre uninstall script to redirect the output of the killall command
will fix this:

preuninstall scriptlet (using /bin/sh):
if [ "$1" -eq 0 ]; then
    export GCONF_CONFIG_SOURCE=`gconftool-2 --get-default-source`
    gconftool-2 --makefile-uninstall-rule \
      /etc/gconf/schemas/gnome-obex-server.schemas > /dev/null || :
    killall -HUP gconfd-2 > /dev/null 2>&1 || :
