It seems the message exists since 2.21.3 (Now I'm not sure anymore whether the call needs to be replaced by something else -- see https://bugzilla.gnome.org/show_bug.cgi?id=583909), but Lucy has 2.21.1 so this patch shouldn't be committed to trunk for now.
AFAIK Lucid has 2.21, so we can't use it while we want to support it.
