A fresh Starbuck install (rh59) with a freshly made non-root user runs gnome-session inside the xterm of a default xinit and pulling up e-conf to select a background pic shows only one large grey area with a small section of magenta instead of the default 4x4 array of pictures and gradients.
I'm not sure how e-conf works with backgrounds, Raster will have to look at this.
Not bug - no backgrounds defined for "clean" theme (well only one - empty bg) because E was not desired to set bg's - can add solid bg colro defsa if wanted.
