Comment 14 for bug 689486

Forget the last comment - I manually changed the icon in '/usr/share/applications/nautilus.desktop' to 'user-home'. -.-

It's not just an unstable-to-unstable issue: when a user unpins the launcher item, then there's only this complete reset to get the right item back (if you don't want to fiddle around with dconf-editor & co.). Doesn't sound optimal.
