Note that on Debian/Ubuntu Nautilus is supposed to handle the automounts of things and this was also failing for me as gnome-volume-manager does not even run. I read the source code for those daemons and the patches applied by Debian/Ubuntu until I found the culprit.

The problem seems to be because of Nautilus. I did the following and this fixed it for me:
gconftool-2 --recursive-unset /apps/nautilus cd-burner
gconftool-2 --recursive-unset /apps/nautilus-
pkill nautilus
