Re: GEmblemedIcons help

I opened a bugreport some time ago
http://bugzilla.gnome.org/show_bug.cgi?id=555715 and they answered
that this change is not scheduled, even in glib 3.
Thay also say it is not enough to invalidate the cache, because some
app might have already asked for the special directory before, so they
cannot free the pointer, becouse it could be in use. (bad C!!!!)

Anyway, again, since moving directories is not a common operation, I
think that nautilus has to show a warning, and does not have to deal
with icon changes.
