Hi Bert, John

There is a bug in copy-from-journal, it is adding an additional dot 
before the file extension. Otherwise it is working.

[o...@localhost ~]$ copy-from-journal -o 
07474cf4-4883-4ded-a994-ab5511cfc29c /tmp/test.sb
/home/olpc/.sugar/default/data/07474cf4-4883-4ded-a994-ab5511cfc29c -> 
/tmp/test..sb

My workaround in scratch-activity looks like this:
if [ -n "$object_id" ] ; then
        filename="$SUGAR_ACTIVITY_ROOT/instance/temp.sb"
        copy-from-journal -o "$object_id" "$filename"
        filename="$SUGAR_ACTIVITY_ROOT/instance/temp..sb"
else
        filename=""
fi
# run Squeak VM with Scratch image
exec /usr/bin/squeak \
        -vm-display-X11 \
        -swapbtn \
        -sugarBundleId $bundle_id \
        -sugarActivityId $activity_id \
        ScratchXO.image \
        "$filename"
