Comment 24 for bug 638217

Hey, I was having the same problem also, it looks like the problem is to authenticate into the zeitgeist. I couldn't solve the problem using the command:

zeitgeist-daemon --replace

Because it looks like that the problem is over authenticating into zeitgeist with user+passwd. So I reseted the whole confiurations and it worked for me. I had to put all my passwd's again for the all others programs but I guess is the price to pay for dont entering a default passwd in the ubuntu key-ring from a fresh install

What I did to fix it was to re-install the whole zeitgeist packages and the gnome-activity-journal and deleted the config files from

zeitgeist:

~/.local/share/zeitgeist

activity-journal:

~/.local/share/gnome-activity-journal

and deleted the default gnome key-ring in:

 ~/.gnome2/keyrings/

In the next log-out/restart it will prompt for a new default gnome key-ring passwd and entering in it I could run activity-journal without a problem. I hope this info can help someone else out there that running the replace for zeitgeist-daemon dont work
