Code review comment for lp:~ricardo.teixas/ubuntu/raring/xfce4-session/fix-for-1104435

Therefore, an error occurring, as described herein: https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1104435, after use of the solution described here: https://bugs.launchpad.net/ubuntu/+source/xfce4-session/+bug/1104435/comments/19, I can say that after several days use ubuntu, the problem never occurred, meaning that the patch removes the error.
