Comment 35 for bug 460483

Evolution recently received a truckload of code changes in preparation for Gnome 3.0 and all deprecations it will introduce (http://people.gnome.org/~fpeters/reports/299.html), which includes moving from Bonobo to D-Bus. Might be a start, but the whole thing is probably still in its infancy. 2.30 was not even included in Lucid.
