Zeitgeist does not seem to be operating in Linux Mint
 

I'd like to try out Zeitgeist Datahub. I am trying this on a new installation of Linux Mint.

I've installed the gnome-activity-journal package, but when I run the activity journal, it doesn't show that I've done anything. I installed the activity log manager and verified that logging is turned on... but still nothing's showing up.

I see no evidence that Zeitgeist has crashed. What am I missing?
