Code review comment for lp:~jelmer/bzr-dbus/zeitgeist

This adds support for providing events to zeitgeist to the dbus plugin. Talking to zeitgeist is done through a small Python wrapper around the dbus Python module, but that python module should always be installed when zeitgeist itself is installed.

This allows showing bzr commits in gnome-activity-journal.

It's based on Markus Korn's initial plugin that is living in a separate Bazaar branch, but is not packaged. He is fine with moving this code into bzr-dbus.
