Comment 11 for bug 1076232

Also, I understand that you don't want to have to keep a Nautilus version always slightly ahead (in version number) with tracker support enabled. But what about on the GNOME 3 Next PPA (or whichever PPA that has a newer GNOME version than the current Ubuntu release) you build nautilus with tracker support. For example, on the upcoming Ubuntu 13.10, nautilus will always be at version 3.8.x WITHOUT tracker support. But whoever uses the GNOME 3 Next PPA will have nautilus 3.10.x. That 3.10.x version could be built with tracker support without the "fear" of the main Ubuntu nautilus version (3.8.x WITHOUT tracker support) replacing it. The new nautilus is from a newer version of GNOME so it will always be kept instead of the default one.

Just think about it... at least whoever wants to be on the latest GNOME stable release will have Nautilus and the Activities overview with all of its goodies enabled.
