[Sugar-devel] Error on running sugar-activity

Thanks.  With datastore not running, expected symptoms are as you say;
activities are not shown, and activities cannot be started.

(Colour of icon in home view is determined by existence of a journal
object for that activity, so before home view is shown the journal
must be searched for matching objects.  The journal is held by the
datastore.)

However, I am surprised at your shell.log, for three reasons;

1.  it does not show any errors about trying to contact the datastore.

2.  the timestamp in the file of 1564399715.389937 is 29th July at
4:58pm, which was 2.65 days ago, yet the traceback was from 31st July
at 10:17am.

3.  it shows Sugar was being started on an X11 display that already
has a window manager; normally Sugar is run on a display with no
window manager, and this may imply you are starting Sugar from a
Terminal instead of from an X session or login greeter.

On the theory that the datastore is failing to start, please test
again by one or more of;

(a) looking at apport /var/crash to find evidence confirming failure,

(b) temporarily excluding Sugar and activities, using instead the
copy-to-journal tool provided by the datastore,

(c) deinstalling the /usr/local datastore and reinstalling the
packaged datastore,

(d) running the datastore by hand instead of requiring D-Bus to start
it, and look for errors.

Hope that helps.
