Cannot make edits- WARNING **: Could not connect: Connection refused

Tried to add 'truecrypt' to unity whitelist, using dconf-editor. When adding it to the list of items, it immediately reverts to previous state.

I saw some errors using other programs to indicate that dbus is not running. I don't know if these problems may be related.

At the bottom, I have the related output of gsettings. Here is the output of dconf-editor

a@EMONSTER:~$ dconf-editor
