Gnome Activity Journal stalls

I installed gnome-activity-journal, restarted zeitgeist and launched gnome-activity-journal, and the app just loads without ever displaying anything. I tried the latest version from the PPA: ii zeitgeist 0.8.2-0ubuntu1~ppa1~natty event logging framework ii zeitgeist-core 0.8.2-0ubuntu1~ppa1~natty event logging framework - engine ii gnome-activity-journal 0.6.0-0ubuntu1~natty1~ppa graphical user interface for Zeitgeist But the result is the same: The daemon says: [DEBUG - zeitgeist.engine] Found 0 events in 0.000194s [DEBUG - zeitgeist.engine] Found 53 events in 0.000753s [DEBUG - zeitgeist.engine] Got 0 raw events in 0.000776s [DEBUG - zeitgeist.engine] Got 53 events in 0.000109s [DEBUG - zeitgeist.engine] Where time spent in _get_event_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in _get_subject_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in apply_get_hooks in 0.000000s [DEBUG - zeitgeist.engine] Found 28 events in 0.000766s [DEBUG - zeitgeist.engine] Got 0 raw events in 0.000444s [DEBUG - zeitgeist.engine] Got 28 events in 0.000113s [DEBUG - zeitgeist.engine] Where time spent in _get_event_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in _get_subject_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in apply_get_hooks in 0.000000s [DEBUG - zeitgeist.engine] Found 236 events in 0.001218s [DEBUG - zeitgeist.engine] Got 0 raw events in 0.003643s [DEBUG - zeitgeist.engine] Got 236 events in 0.000178s [DEBUG - zeitgeist.engine] Where time spent in _get_event_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in _get_subject_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in apply_get_hooks in 0.000000s [DEBUG - zeitgeist.engine] Found 115 events in 0.000892s [DEBUG - zeitgeist.engine] Got 0 raw events in 0.001598s [DEBUG - zeitgeist.engine] Got 115 events in 0.000118s [DEBUG - zeitgeist.engine] Where time spent in _get_event_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in _get_subject_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in apply_get_hooks in 0.000000s [DEBUG - zeitgeist.engine] Found 10 events in 0.000587s [DEBUG - zeitgeist.engine] Got 0 raw events in 0.000191s [DEBUG - zeitgeist.engine] Got 10 events in 0.000102s [DEBUG - zeitgeist.engine] Where time spent in _get_event_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in _get_subject_from_row in 0.000000s [DEBUG - zeitgeist.engine] Where time spent in apply_get_hooks in 0.000000s [DEBUG - zeitgeist.engine] Found 0 events in 0.000665s [DEBUG - zeitgeist.fts] Indexing 'file:///home/raphink/Pictures/stalled_activity_journal.png' [DEBUG - zeitgeist.fts] Indexing 'file:///home/raphink/Pictures/stalled_activity_journal.png' [DEBUG - zeitgeist.fts] Indexing 'file:///home/raphink/Pictures/stalled_activity_journal.png' [DEBUG - zeitgeist.engine] Inserted 3 events out of 3 in 0.207549s [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/1 [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/3 [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/2 [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/5 [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/4 [DEBUG - zeitgeist.notify] Checking monitor :1.146/org/gnome/zeitgeist/monitor/6 [DEBUG - zeitgeist.notify] Notifying :1.146/org/gnome/zeitgeist/monitor/6 about 3 insertions [DEBUG - zeitgeist.fts] Committing FTS index [WARNING - zeitgeist.notify] Failed to deliver notification: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. Any idea what's wrong?
