I had the same problem and here is what I did:

bz@orion:~ > cd ./.local/share/kactivitymanagerd/resources
bz@orion:~/.local/share/kactivitymanagerd/resources > ll

drwxrwxr-x 4 bz users   4096 Oct 17 09:54 **.**

Look at your errors.log. Kill the current kactivitymanagerd, remove the 3 files database, database-shm, database-wal, and restart the kactivitymanagerd daemon by user. It recreates all the files clean, and I did not get the error message again.

Thanks, that did it. Navigating to ~/.local/share/kactivitymanagerd/resources and deleting database + database-shm + database-wal makes the crashes go away. Only annoyance was that all favorites were removed from the kickoff launcher and I had to add them back in, other than that all is working well once more.
