Please describe the problem:
In Nautilus, the background of icon views can be set by dragging and dropping
from the "Backgrounds and Emblems" dialog. However, this doesn't work for tree
views. They are always displayed in the GNOME default style.

Steps to reproduce:
1. In Nautilus, click View->List view.
2. Open Edit->Backgrounds and Emblems.
3. Drag a background to the list view.


Actual results:
List view background stays the default.

Expected results:
List view background is changed according to the selected color or picture.

Does this happen every time?
Yes.

Other information:
I guess this is because the GtkTreeView can't be styled (apart from the general
GNOME skinning). I guess the desired behaviour would be not so easy to implement
for background bitmaps.
