The bug description implies that the filesystem would have to have been idling from the point where the affected files were written until the point of the system crash (or unclean unmount), such that the old, and by that time incorrect, metadata updates would still linger in the journal, but that was not really the case here. The filesystem was quite busy during those weeks.... Also, the bug report speaks only of zero-length files, while many of our files had been truncated to lengths other than zero.
