Comment 5 for bug 69938

I have noticed this problem as well. Or something similar. The background wallpaper is replaced with the Ubuntu 'default' background when I start Rhythmbox and, in addition, when I start Nautilus.

In addition, fluxbox actions that require the desktop no longer work. For example, right clicking the desktop should bring up the Root Menu (or at least with the default setup) but it does not. I am still able to bring up the RootMenu using a hotkey. Other actions that require a click on the desktop no longer work. I've also noticed that it interferes with conky. The Ubuntu 'default' background goes over top of the conky output, for lack of a better description.

I've noticed this in both Hardy Heron and in Jaunty Jackalope Alpha 4 (although the conky problem does not happen in Jaunty Jackalope).
