Things have changed slightly: I implemented Mikkel's suggestion of setting the version to -1 just before an upgrade, and back to it's correct value afterwards. This is only useful if an upgrade is killed: the upgrade can also fail due to a raised OperationalError. If that is the case (regardless of whether or not the corruption comes from a bad database creation), we allow the code to fall through the statements in create_db, which safely restores the database.

And because the GUI does not report that zeitgeist faiiled to run, applications that rely on zeitgeist simply fail to work without any relevant reason given. I ran into this problem on upgrading an installation from Ubuntu 10.04 to 10.10. After the upgrade, the dockbarx applet failed to run. The error message from gnome-panel just said it had failed to run, and .xsession-errors said the child process did not report any specific error. Running in debug mode (ie with the command "dockbarx-factory.py run-in-window") gave: ERROR:dbus.proxies:Introspect error on :1.134:/org/gnome/zeitgeist/log/activity: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus) DEBUG:dbus.proxies:Executing introspect queue due to error Traceback (most recent call last): File "/usr/bin/dockbarx_factory.py", line 26, in <module> import dockbarx.dockbar ...

I fixed the problem (eventually) by deleting the zeitgeist database file and restarting the zeitgeist- daemon manually. What I would expect to happen is: 1) The GUI should report that zeitgeist has failed to run. 2) Better yet, zeitgeist could create the necessary tables if its database is invalid or perhaps backup the old database and create a new one so it can run properly. It would of course be nice if dockbarx reported better error information, but since there are other applications that depend on zeitgeist, it would be good if zeitgeist could recover from this situation.
