have you reported the crashes in trackerd? (crashes in tracker-extract are irrelevant as it will self destruct if it takes too much memory or takes too long to extract metadata this is a deliberate feature and not a bug!)
wrt not working - this could be because of bugs in the DB from 0.6.3 version. To repair simply call trackerd --reindex from terminal
