I've done a fresh setup of Xubuntu 12.10 on a 32bit machine, but changed to Gnome-Shell 3.6.2.
When hitting the activities button, only documents or contacts search provide results, files or folders do not show up - no Downloads, Documents, Videos or similar folder. Tracker-miner is running properly and there aren't any locations excluded from the search pattern.
What I've found out after adding the Gnome3-PPA: With Nautilus 3.4.2 neither files nor folders show up. When upgrading Nautilus to 3.6.3, at least my favourites (Documents, Downloads) show up, but no subfolders or files are included. Also, tracker search does not give back any proper results, although the folders are marked as recursive.
Where could I look for additional settings?
