--------------------+-------------------------------------------------------
 When an activity has no dbus implementation, it can be started but sugar
 is not able to manager the changed of the zoom view using keyboard or
 mount (move on the upper-left side of the screen).

 Here you can find the shell.log file.

 I use the latest joyride build with security disabled (rm /etc/olpc-
 security), otherwise my activity not start.

 You find the activity used as test here:
