Deskbar-applet does not recognize Tracker if dbus-python is not installed. Ebuild should have dbus-python as a dependency Reproducible: Always Steps to Reproduce: 1.Install tracker and deskbar-applet with no dbus-python 2.Look for tracker in preferences of deskbar-applet (It is not there) 3.
The problem is that the python bindings used to be part of the dbus package, but were split out. This is fixed in 2.18 in the overlay, but not backported. I've fixed this in 2.16.2-r1, so you'll have to resync and update that.
