We were debugging this with Natalia, it seems to be an issue with Zeitgeist unable to start, because it was being used on Natty and then directly with Precise, so the schema was never updated from ver 3 (which would happen if Oneiric was installed), and latest Zeitgeist can't upgrade schema ver 3 or older.
As a workaround for now you can remove the Zeitgeist DB (`rm ~/.local/share/zeitgeist/activity.sqlite`), we'll make an SRU for zeitgeist where the old upgrade path will be re-added.
