This bug is fixed as far as I know. If you still have a problem with xfce4-volumed, please report a new bug to your distribution (using ubuntu-bug in your case). Also, make sure you attach ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-mixer.xml and make sure you do NOT have pulseaudio installed / running when the crash occurs.
