Comment 8 for bug 651689

I noticed that Faenza, Gnome (obviously), and ubuntu breathe icon themes show the appropriate icons for special folders. Tango does not. YAMA retrieves the icons via GIO (some IO library of Gnome) and, although I don't know how Cairo Menu does it, it also happens in Cairo Menu. So I think the icon themes (Tango and oxygenrefit, and probably more) are the culprit.

I'll commit a fix (fallback to "image-missing" icon) soon.
