Colin Watson has fixed the disgusting icons on GTK1. His patch

appears to merely fix the background colour (arranging for it to
have transparency rather than being on some kind of default grey
background), but it turns out to also fix the strange blurry
behaviour I see in the GNOME Taskbar, for no very obvious reason.
