Comment 5 for bug 1464933

Wow this log files indicates a corrupt Zeitgeist database.

Best we try to reset it and see whether this solves the problem.

First close Diodon and then run the following commands:
mv ~/.local/share/zeitgeist/ ~/.local/share/zeitgeist-old
zeitgeist-daemon --replace

and then start Diodon again and observe whether it solves the problem. If not we have to investigate further.
