New description:

 Terminal-41 starts fine from a new session, but fails when resumed with
 previous saved state. New activity state is not being saved.

 Here's a trace back after a resume from a Terminal-40 saved state:

 {{{

   File "/usr/lib/python2.7/site-packages/sugar3/activity/activity.py",

     vt.feed(l + '\r\n')
   File "/usr/lib/python2.7/site-packages/gi/types.py", line 47, in

Comment(by garycmartin):

 OK looks like a bug with resume saved state, and state saving, nothing to
 do with XO-4 hardware.
