I think it's not a bug in light-themes.

I think the ubuntu software center is using a background-color, overriding gtk theme ones, thus it colors the progressbar.
With Adwaita the problem is not noticeable because Adwaita is using a background-image, which in Gtk+ rendering has higher priority over background color.
