Comment 9 for bug 839775

@Ilya: Search-related icons were removed from Humanity the day before UI Freeze because they had low contrast with Ambiance's dark toolbar. Now it's too late to change anything in Natty, the proper fix will be introduced during the Precise cycle (along with many other icon changes).

I reported bug 877451 for other icons that should be added to not-in-humanity.txt.
