gnome-shellなしでメタシティを実行する（gnome 3）

こんにちは、gnome-shellなしで複合マネージャとしてメタシティをどのように使用できますか？私のカスタムxsessionでこれをやろうとしています。

#!/bin/bash
if test -z "$DBUS_SESSION_BUS_ADDRESS"; then
eval `dbus-launch --sh-syntax --exit-with-session`
fi

metacity --replace ccp & wmpid=$!
xsetroot -solid white &
sleep 1
if [ -f ~/.metacity-session ]; then
source ~/.metacity-session &
else
xterm &
fi
# Wait for WM
wait $wmpid

しかし、私の〜/.xsession_errorsにはこれがあります。

Fedora 17で実行しています。私が逃したものは何ですか？
