disk-full causes data store not to respond anymore

[sascha_silbe]

After a xapian.DatabaseError due to disk-full, sugar-datastore stopped responding via dbus:

DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name :1.4 was not provided by any .service files

No index rebuild happened on restart (I sorted out the disk-full condition manually before restarting).

This is with the version support branch of sugar-datastore, but I don't expect the mainline one to behave differently.

Patchseries addressing this is in sugar-devel.
