Comment 8 for bug 1954954

I do not think those files have anything to do with it. Zeitgeist stores is data at `~/.local/share/zeitgeist` so once you have the error you could simply delete it and start Diodon again like the following:

killall diodon
killall zeitgeist-daemon
rm -R ~/.local/share/zeitgeist
-> Start Diodon through the Menu

What you could also try is to tell Zeitgeist not to persist the data on the file system but in memory (this means that after a reboot the history will be gone - this is just a suggestion for testing). You can do this with the following command:

echo "ZEITGEIST_DATABASE_PATH=:memory:" >> ~/.pam_environment

after that you need to reboot.
