[Sugar-devel] dbus exception

[Tony Anderson]

Hi, Gonzalo

Sadly, the log shows nothing. I get the exception on a
     try:
         datastore.get(obj) (where obj = olpcgames.ACTIVITY.game_handle)

where the activity uses the standard olpcgames activity.py,

the activity.py in olpcgames has:

def __init__(self, handle):

if handle.object_Id:
     self.game_handle = handle.object_id

along with some magic code (def make_global)  to make olpcgames.ACTIVITY 
refer to 'self'.

The activity is derived from the one in ASLO, but I added the ability to 
start a quiz by resume from the Journal so this datastore usage is not 
in that
version. However, this code worked in 13.2.2.
