Code review comment for lp://staging/~jassmith/desktop-switcher/dust-fix

Includes an incredibly lame fix to select Dust of Human-Murrine-Netbook. I chose this route over resetting gconf defaults because that method, upon testing, has resulted in setting the wrong theme on a box that was originally a desktop install. I think the proper solution is as mentioned in the related bug report different sessions, and for now we should use this solution.
