Can't open Rhythmbox, Totem, Nautilus
I have Fedora 12 in my laptop. I can't open rhythmbox, totem movie player, nautilus etc. If I try to open through terminal, it reports that
Warning: Unable to create "trees" RDF storage.
Performance can be improved by upgrading librdf.
I have installed all plugins for playing multimedia files.
I searched for my problem but I could not find any solution. In addition to this I could not see any icons in GNOME desktop environment. If I try to open computer through PLACES in menu bar it reports that File Manager not responding.
Please somebody help me to solve my problem.
