Comment(by tomeu):

 Thanks for the explanation.

 This ticket exists because we have no strategy for coping with format
 changes in the xapian index used by the datastore. This should not cause
 any issue in the field if we don't upgrade to a higher version of the
 xapian engine.

 This ticket is referred in the Test Group Release Notes because, by
 mistake, the xapian engine got upgraded from 1.0.2 to 1.0.4 during the
 builds 669-680.

 In a future implementation of the DS, I hope we store the metadata in a
 less fragile way and use indexes just for speeding up lookups.
