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.

Hi Tony,
Could you attach log files and link to the activity version you are using?
The information provided is not enough to guess what is happening
"DBusException('Did not receive a reply, ...)." means the datastore is not replying,
(or is taking a too log time) but why that is happening is not clear.

    Another problem. The Quiz activity crashes in various ways. On
    some occasions, it completes normally.
    The log shows no error messages. However, it reports in some cases
    terminated with  signal 6 or signal 11.

    Using try, I was able to narrow it down to a datastore.get. The
    exception is 'dbus.exceptions.DBusException'>,
    DBusException('Did not receive a reply, ...).

    I assume the lack of error messages relates to the same
    problem, the error occurs in a different process.

    I have also seen an isolated (preceded and followed by unrelated
    messages from the activity) message in the log:

    Fatal Python error: (pygame parachute) Segmentation fault

    In this case, the log reported a signal 6.
