Comment 3 for bug 1885092

Thanks for the update. This makes more sense.

Not sure whether this is a general issue with Zeitgeist on 20.04 or you might have a corrupted database.

Could you try the following:

killall zeitgeist-daemon
killall diodon
mv .local/share/zeitgeist/ .local/share/zeitgeist.old
diodon

and see whether this solves the issue?
