        Propagate index errors up to the GUI, so the user has the opportunity
        to trigger a reindex.

        * src/libtracker-db/tracker-db-index.[ch]: Add an "error-received"
        signal. Emit it when QDBM fails to store a word.

        * data/dbus/tracker-indexer.xml:
        * src/tracker-indexer/tracker-marshal.list:
        * src/tracker-indexer/tracker-indexer.[ch]: Add an "IndexingError"
        DBus signal. Propagate up index errors.

        * data/dbus/tracker-daemon.xml:
        * src/trackerd/tracker-dbus.c:
        * src/trackerd/tracker-daemon.c:
        * src/trackerd/tracker-marshal.list: Add an "IndexingError" signal.
        Listen to that signal from the indexer in order to propagate it up the
        stack.

        src/tracker-applet/tracker-applet.[ch]: Listen for the new signal, and
        display an error notification with an option to reindex from scratch.
