I'm closing this bug since it has been fixed both in Zeitgeist (by always committing removals) and in GNOME Activity Journal (by removing all events in the same day part).
Stefano, please open a new bug about your issue, against Zeitgeist Data-sources. IMHO the Bazaar plugin should be fixed to give each revision a different URI, possibly including the revision ID.
