Comment 9 for bug 549552

> I was proposing to make the background tab work just like this ("Use background settings from system theme"). I'm not sure of how else to do implement this when there are 2 sources for the background configuration (gconf and gtkrc), without making it very fragile. The issue I have is trying to work out where to take the configuration from (eg, if the user selects transparent, should the transparency be set to the value of the slider, or the value in the theme?)

This makes a lot of sense. The connection to the theme is really not obvious at present.
