Information dialog that should appear when "Allow Xfce to manage desktop" is _disabled_ in Desktop preferences popups when it's _enabled_. Quite sure this is not wanted behaviour. http://dev.gentoo.org/~betelgeuse/xfce-desktop-manage.png
Yes, the idea was to avoid adding a string so close to the 4.4 release, and switch to the new string after it had been translated.
Removing this in 4.6 entirely, so moot point. Not interested in fixing for 4.4 branch.
