The idea is to use GtkTreeView instead of GtkCList. Though I think
it'll be quite some time before clist actually disappears, since it's
widely used.

FWIW GtkTreeView has real toggle cells, so no need for the pixmap
hacks with it.

CList shouldn't have changed behavior - if you have a simple test
case, maybe file a bug report on bugzilla.gnome.org so we can see
what's wrong.
