zeitgeitst-datahub showing: "IndexError: list index out of range"

I got the code from bzr, the last revision from the log is 1505. After I installed zeitgeist I ran:

python zeitgeist-daemon.py
python zeitgeist-datahub.py

In different terminals. zeitgeist-daemon seems to capture events correctly but there is something wrong with zeitgeist-datahub, here is the terminal output:

IndexError: list index out of range

What am I doing wrong?

Initially, from ppa packages on two different computers, GAJ did not show any entries, just "pinned items". I ran these commands because I saw the answer to question #99109, no luck with any version (ppa or bazar).

Thanks in advanced.
