The cause of the problem perhaps might be similar to the one here: http ://gnome-tomboy.1788872.n4.nabble.com/compiling-running-issues-on- Ubuntu-11-10-td4605044.html. I don't remember the exact mechanics, but somehow Unity is provided with that variable when it starts "regularly" from lightdm, gdm, etc, and when it isn't, the variable isn't inherited with the required value for interproccess communication.
