pkill diodon
pkill zeitgeist-daemon

sqlite DB broken

• For whatever reason, even a sqlite database might break.
• If zeitgeist does not work, than diodon does not work.

# Testrun from diodon shows:
$ strace diodon
...
zeitgeist-clipboard-storage.vala:383: Add item unavailable not successful, error: GDBus.Error:org.gnome.zeitgeist.EngineError.DatabaseCorrupt: Database corruption flag is set.
...

• Check the zeitgeist db:

$ sqlite3 ~/.local/share/zeitgeist/activity.sqlite 'VACUUM;'

• If this reports something like Unable to execute SQL: - this is the problem.
• Check zeitgeist:

$ zeitgeist-daemon -r
[09:25:01.337402 WARNING] sql.vala:150: It looks like your database is corrupt. It will be renamed and a new one will be created.
[09:25:01.391462 WARNING] zeitgeist-daemon.vala:546: Can't create database: 10, disk I/O error

• If the past user activity is not important anymore, remove the broken db

$ pkill zeitgeist-daemon
$ rm -r .local/share/zeitgeist/
$ nohup zeitgeist-daemon -r &

# Restart diodon
$ pkill diodon
$ nohup diodon &
