Comment(by godiard):

 This is difficult to reproduce in a desktop, but in the XO is more common.
 The easier way to trigger it is press two or three clicks very quickly
 over a activity icon in the home view. The result is more than one icons
 in the frame, only the first with a palette, and the others continue
 pulsing forever and in the palette only have a text "Starting.."
 I reproduced it with the Read activity many times.

 If you check ps, will see many python process started (one for every
 icon).

 The problem we have is, we are using the activity_id in the shell model to
 list and manage the activities, but in this case, there are many instances
 of the activity with the same activity_id.

 I resolved add a way to close this process, because I saw more than one
 sources of this issue. We must try to solve the issues in the activities,
 but also we need a way to kill the process.

 My patch add the pid to the dbus calls, and use this information in the
 shell. Also use kill to finish a activity, I don't know if this is the
 right solution, but in my tests, the activities associated to the pulsing
 icons do not have a window.
