This happened to me a few times during the last few days, each time after I restarted Sugar rather quickly. There's an exception in the log: 1285265788.580216 DEBUG root: max_versions=0 1285265788.604839 ERROR root: Failed to open index, will rebuild Traceback (most recent call last): File "/home/sascha.silbe/sugar-jhbuild/install/lib/python2.6/site-packages/carquinyol/datastore.py", line 275, in __init__ self._index_store.open_index() File "/home/sascha.silbe/sugar-jhbuild/install/lib/python2.6/site-packages/carquinyol/indexstore.py", line 246, in open_index self._database = WritableDatabase(index_path, xapian.DB_CREATE_OR_OPEN) File "/usr/lib/python2.6/dist-packages/xapian/__init__.py", line 4059, in __init__ _xapian.WritableDatabase_swiginit(self,_xapian.new_WritableDatabase(*args)) DatabaseLockError: Unable to get write lock on /home/sascha.silbe/.sugar/default/datastore/index: already locked 1285265789.971570 DEBUG root: Going to update the index with object_ids [('15947ca6-a018-47d0-9c09-f58c12e6cf82' [...] My guess is that the old sugar-datastore instance still has the index open. We don't have API for stopping sugar-datastore and instead rely on dbus-daemon to stop it when it gets stopped itself. I've noticed that when using --exit-with-session dbus-launch and dbus-daemon often continue to run for several seconds after a session has ended and returned. So this is just another way to trigger SL#1257 [1]. It might be even easier to trigger if you're running sugar-emulator from a GUI menu on a slow system as the user assumes it to be finished as soon as the Xephyr window is closed, not when sugar-emulator (the script) stops.
