I'm re-opening this since I've finally found the cause of this problem! When events are deleted, interpretations/manifestations/mimetypes/etc. which are no longer used are automatically removed from the database. However, the cache isn't informed about this and until Zeitgeist is restarted it'll continue using the IDs of the deleted rows for new events.
(I'm setting the importance down since a workaround for the problem is already deployed). ** Changed in: zeitgeist Importance: High => Medium ** Changed in: zeitgeist Status: Fix Released => Triaged -- You received this bug notification because you are a member of Zeitgeist Framework Team, which is subscribed to Zeitgeist Framework. https://bugs.launchpad.net/bugs/598666 Title: Invalid cache access (was: Error when trying to fetch items) Status in Zeitgeist Framework: Triaged Bug description: When i try to fetch all items in one query i get Error from Zeitgeist engine: org.freedesktop.DBus.Python.KeyError: Traceback (most recent call last): File "/usr/lib/pymodules/python2.6/dbus/service.py", line 702, in _message_cb retval = candidate_method(self, *args, **keywords) File "/usr/local/share/zeitgeist/_zeitgeist/engine/remote.py", line 254, in FindEvents event_templates, storage_state, num_events, result_type, sender)) File "/usr/local/share/zeitgeist/_zeitgeist/engine/main.py", line 378, in find_events return self._find_events(1, *args) File "/usr/local/share/zeitgeist/_zeitgeist/engine/main.py", line 366, in _find_events return self.get_events(rows=result, sender=sender) File "/usr/local/share/zeitgeist/_zeitgeist/engine/main.py", line 188, in get_events events[event.id].append_subject(self._get_subject_from_row(row)) File "/usr/local/share/zeitgeist/_zeitgeist/engine/main.py", line 160, in _get_subject_from_row getattr(self, "_" + field).value(row["subj_" + field])) File "/usr/local/share/zeitgeist/_zeitgeist/engine/sql.py", line 422, in value return self._inv_dict[id] KeyError: 138 This looks serious _______________________________________________ Mailing list: https://launchpad.net/~zeitgeist Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~zeitgeist More help : https://help.launchpad.net/ListHelp
